IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS

FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON JUNE 16, 2023

The Proxy Statement and Annual Report to Stockholders are available at

https://t-mobile.com/Proxy2023 and https://www.proxyvote.com.

Cautionary Statement Regarding Forward-Looking Statements

This Proxy Statement includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

All statements, other than statements of historical fact, including information concerning our future results of operations, are forward-

looking statements. These forward-looking statements are generally identified by the words “anticipate,” “believe,” “estimate,”

“expect,” “intend,” “may,” “could” or similar expressions. Forward-looking statements are based on current expectations and

assumptions, which are subject to risks and uncertainties that may cause actual results to differ materially from the forward-looking

statements, including unexpected delays, difficulties, and expenses in executing against our environmental, climate, diversity and

inclusion or other “Environmental, Social, and Governance (ESG)” targets, goals and commitments outlined in this document,

including, but not limited to, our efforts to reduce our greenhouse gas emissions, as well as changes in laws or regulations affecting

us, such as changes in cybersecurity, data privacy, environmental, safety and health laws, and other risks as disclosed in our most

recent annual report on Form 10-K and other filings with the Securities and Exchange Commission (the “SEC”). Given these risks and

uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. T-Mobile does not undertake,

and expressly disclaims any duty, to update any statements contained herein, whether as a result of new information, new

developments, or otherwise, except to the extent that disclosure may be required by law. In addition, some of the statements

contained in this Proxy Statement may rely on third-party information and projections that management believes to be reputable;

however, T-Mobile does not independently verify or audit this information, and any inaccuracies or deviations in such information and

projections may materially impact our ability to execute on our strategy, achieve our goals, or otherwise adversely impact our business.

This Proxy Statement contains ESG-related statements based on hypothetical scenarios and assumptions as well as estimates that are

subject to a high level of uncertainty, and these statements should not necessarily be viewed as being representative of current or

actual risk or performance, or forecasts of expected risk or performance. In addition, historical, current, and forward-looking

environmental and social-related statements may be based on standards for measuring progress that are still developing, and internal

controls and processes that continue to evolve. For example, our disclosures based on existing standards may change due to revisions

in framework requirements, availability of information, changes in our business or applicable government policies, or other factors

which may be beyond our control. Forward-looking and other statements in this document may also address our corporate

responsibility and sustainability progress, plans, and goals. Our inclusion of such ESG-related information herein or in other

documents is not necessarily “material” under the federal securities laws for SEC reporting purposes, even if we use the word

“material” or “materiality” in relation to those statements, but is informed by various ESG standards and frameworks (including

standards for the measurement of underlying data), and the interests of various stakeholders. Website references throughout this

document are provided for convenience only, and the content on the referenced websites is not incorporated by reference into this

document.

PROXY STATEMENT 2023

Proxy Statement Summary

Good Corporate Governance Practices

Governance is real at T-Mobile. We became a publicly traded company in 2013 with a significant s tockholder, Deutsche Telekom AG

(“Deutsche Telekom”) following a business combination with MetroPCS Communications, Inc. (the “Metro Combination”). On April 1,

2020, we completed the merger with Sprint Corporation (“Sprint”) in an all-stock transaction (the “Sprint Combination” or the

“Merger”). Immediately after the Sprint Combination, we had two significant stockholders, Deutsche Telekom and SoftBank Group

Corp. (“SoftBank”). In connection with the Sprint Combination, on April 1, 2020, Deutsche Telekom and SoftBank entered into a

Proxy, Lock-up and ROFR Agreement (the “SoftBank Proxy Agreement”), and on June 22, 2020, Deutsche Telekom, Marcelo Claure

and Claure Mobile LLC (“Claure Mobile”), a Delaware limited liability company wholly owned by Mr. Claure, entered into a Proxy,

Lock-up and ROFR Agreement (the “Claure Proxy Agreement” and together with the SoftBank Proxy Agreement, the “Proxy

Agreements”). As a result of the Proxy Agreements, as of March 31, 2023, Deutsche Telekom has voting control over approximately

54.0% of the outstanding T-Mobile common stock, including approximately 0.4% and 3.3% shares of the outstanding T-Mobile

common stock held by Claure Mobile and SoftBank, respectively.

Deutsche Telekom has the right to designate 10 of our directors. A s a result, we have stockholder representation on our Board. The

Nominating and Corporate Governance Committee has the right to designate three of our directors, all of whom are independent

based on the applicable NASDAQ and SEC rules. Directors approach each Board decision with a mindset that is intellectually

independent from management. In addition, our Board has structured our corporate governance program to promote the long-term

interest of stockholders, strengthen the Board’s and management’s accountability and help build public trust in the Company.

Proxy Statement Summary

T-MOBILE DELIVERS INDUSTRY-LEADING CUSTOMER, POSTPAID

SERVICE REVENUE AND CASH FLOW GROWTH IN 2022

Our differentiated growth strategy drove industry-best growth in postpaid net account additions of 1.4 million

, postpaid net customer

additions of 6.4 million and High Speed Internet net customer additions of 2.0 million in 2022. We ended 2022 with a record high in

total customers of 113.6 million.

Our record customer growth translated into industry-leading postpaid service revenue and cash flow growth in 2022. We ended 2022

with total service revenues of $61.3 billion, postpaid service revenues of $45.9 billion, net income of $2.6 billion, Core Adjusted

EBITDA of $26.4 billion, net cash provided by operating activities of $16.8 billion and Free Cash Flow of $7.7 billion. We realized

approximately $6.0 billion of synergies from the Sprint Combination in 2022.

We further extended our reputation for value while translating our 5G lead into overall network leadership for the first time, as noted by

multiple third parties. At the end of 2022, our 5G network covered 325 million people (98% of Americans), and our super-fast Ultra

Capacity 5G covered 263 million people nationwide.

Our stock price increased by 64.5% from April 1, 2020 (the closing date of the Sprint Combination) to December 31, 2022.

Core Adjusted EBITDA and Free Cash Flow are non-GAAP financial measures. Each of the non-GAAP financial measures should be

considered in addition to, but not as a substitute for, the information provided in accordance with U.S. generally accepted accounting

principles (“GAAP”). Reconciliations to the most directly comparable GAAP financial measures are provided in Appendix A to this

Proxy Statement. Additionally, starting in the first quarter of 2023, we have renamed Free Cash Flow to Adjusted Free Cash Flow. This

change in name did not result in any change to the definition or calculation of this non-GAAP financial measure.

PROXY STATEMENT 2023

Corporate Governance at T-Mobile

About the Board of Directors

GOVERNANCE FRAMEWORK AND CODE OF BUSINESS CONDUCT

Our Board has adopted Corporate Governance Guidelines that, together with our certificate of incorporation, our bylaws and the

Second Amended and Restated Stockholders’ Agreement we entered into with Deutsche Telekom and SoftBank on June 22, 2020 (the

“Stockholders’ Agreement”), provide a framework for the effective governance of the Company.

The Board also adopted our Code of Business Conduct, which establishes the standards of ethical conduct applicable to our

directors, officers and employees. In addition, we have a Code of Ethics for Senior Financial Officers. In the event of a waiver by the

Board of any provisions of the Code of Business Conduct or Code of Ethics for Senior Financial Officers applicable to directors or

executive officers or any amendment thereto, we will promptly disclose the Board’s actions on our website.

OUR BOARD

Our Board currently consists of 13 directors. One of the directors is currently employed by the Company. We are required to have a

“National Security Director” pursuant to our national security commitments entered into in connection with the Sprint Combination.

Letitia A. Long currently serves in such capacity. Pursuant to our certificate of incorporation and the Stockholders’ Agreement,

Deutsche Telekom has certain rights to designate director nominees and to have such designees serve on the committees of the

Board. See “Transactions with Related Persons and Approval—Transactions with Deutsche Telekom and SoftBank—Stockholders’

Agreement” for more information.

WE ARE A CONTROLLED COMPANY WITH CERTAIN EXEMPTIONS

Pursuant to the Proxy Agreements, Deutsche Telekom has voting control, as of March 31, 2023, over approximately 54.0% of the

outstanding shares of our common stock (including approximately 0.4% and 3.3% of the outstanding shares of common stock held by

Claure Mobile and SoftBank, respectively), and we are deemed a “controlled company” under the NASDAQ Stock Market LLC

(“NASDAQ”) rules. These rules exempt “controlled companies,” like us, from certain corporate governance requirements, including:

(i) that a majority of our Board be independent, (ii) that our Nominating and Corporate Governance Committee be composed entirely

of independent directors, and (iii) that our Compensation Committee be composed entirely of independent directors.

DIRECTOR INDEPENDENCE

On an annual basis, our Board evaluates the independence of each director, including nominees for election to the Board, in

accordance with NASDAQ rules and our Corporate Governance Guidelines. For certain types of relationships, NASDAQ rules require

us to consider a director’s relationship with the Company, and also with any parent or subsidiary in a consolidated group with the

Company, which includes Deutsche Telekom and its affiliates. Each of the following directors or director nominees is an “independent

director” under NASDAQ rules and our Corporate Governance Guidelines:

䡵 Marcelo Claure

䡵 Srikant M. Datar*

䡵 Bavan M. Holloway*

䡵 Letitia A. Long

䡵 Teresa A. Taylor*

䡵 Kelvin R. Westbrook

* The Board has determined that each member of the Audit Committee meets the heightened independence criteria applicable to audit committee members under NASDAQ and SEC rules.

BOARD LEADERSHIP

OUR CHAIRMAN AND OUR CHIEF EXECUTIVE OFFICER ROLES ARE SEPARATED

We believe that separating the roles of Chief Executive Officer and Chairman of the Board is appropriate for the Company and in the

best interests of the Company and its stockholders at this time. Timotheus Höttges, Deutsche Telekom’s Chief Executive Officer, is the

Chairman of the Board. Key responsibilities of our Chairman include:

• Managing the overall Board function

• Chairing all regular sessions of the Board

• Establishing the agenda for each Board meeting in consultation with the lead independent director, our Chief Executive

Officer and other senior management, as appropriate

• Assisting in establishing, coordinating and reviewing the criteria and methods for evaluating, at least annually, the

effectiveness of the Board and its committees

PROXY STATEMENT 2023

䡵

Corporate Governance at T-Mobile

Absent any changes to the Stockholders’ Agreement, which will require Deutsche Telekom’s approval, the Company does not foresee

a possibility that the Chairman of the Board and CEO roles will be filled by a single individual. The separation of the offices allows

Mr. Höttges to focus on management of Board matters and allows our Chief Executive Officer to focus on managing our business.

Additionally, we believe the separation of the roles ensures the objectivity of the Board in its management oversight role, specifically

with respect to reviewing and assessing our Chief Executive Officer’s performance. The Board believes that the current leadership

structure chosen by the Board is conducive to the Board’s role in risk oversight. The Company would engage with stockholders prior

to the Board making a decision to combine the Chairman and Chief Executive Officer roles, and would promptly publicly disclose such

a decision by the Board.

WE HAVE A LEAD INDEPENDENT DIRECTOR

Our Board has also chosen to appoint a lead independent director. The lead independent director has significant authority, provides

leadership for our independent directors, and strengthens the Board’s oversight of the Company’s business. Teresa A. Taylor is our

current lead independent director. She also serves as the Chair of Nominating and Corporate Governance Committee. Key

responsibilities of our lead independent director include:

• Coordinating the activities of our independent directors

• Calling and presiding over the executive sessions of the independent directors

• Functioning as a liaison between the independent directors and the Chairman of the Board and/or the Chief Executive Officer

• Providing input on design of the Board

• Providing input on the flow of information to the Board, including the Board’s agenda and schedule

• Facilitating discussion among the independent directors on key issues and concerns outside of Board meetings, including

with respect to risk management

• Chairing the annual stockholders’ meeting when the Chairman of the Board is not present

• When requested, representing the Board with internal and external audiences, including stockholders

BOARD MEETINGS AND DIRECTOR ATTENDANCE

Our Board meets regularly throughout the year. Committees typically meet the day prior to the Board meeting, and, depending on the

schedule of the Board meeting, the Audit Committee holds additional meetings in connection with quarterly earnings releases.

Directors are expected to attend all meetings of the Board and each committee on which they serve, as well as the Annual Meeting. At

each regularly scheduled Board meeting (or more frequently if necessary), time is set aside for executive sessions where outside

(non-management) directors meet without management present. In addition, our Corporate Governance Guidelines require the

independent directors to meet at least twice each year in executive sessions, with the lead independent director presiding at such

executive sessions.

• Our Board met five times during 2022

• Each director attended at least 75% of the total number of meetings of the Board and Board committees on which he or she

served

• All directors who then served on the Board attended our 2022 annual meeting of stockholders

Board Committees and Related Matters

Our Board has six standing committees: Audit, CEO Selection, Compensation, Executive, Nominating and Corporate Governance and

Transaction. The CEO Selection and Transaction Committees were formed upon the Sprint Combination. The Board makes committee

and committee chair assignments annually at its meeting immediately following the annual meeting of stockholders, although further

changes may be made from time to time as deemed appropriate by the Board.

Each committee has a Board-approved charter, which is reviewed annually by the respective committee. Recommended changes, if

any, are submitted to the Board for approval. Each committee may retain and compensate consultants or other advisors as necessary

for it to carry out its duties, without consulting with or obtaining the approval of the Board or the Company. A copy of the charter for

each standing committee can be found on the Investor Relations section of our website at http://investor.t-mobile.com by selecting

Compensation Committee in its evaluation of the compensation and benefits provided to the Chief Executive Officer and the other

executive officers. Mercer generally attends Compensation Committee meetings at which executive officer compensation is discussed

and provides information, research and analysis pertaining to executive compensation as requested by the Compensation Committee.

Mercer also updates the Compensation Committee on market trends. During 2022, the aggregate fees for such services were

approximately $321,000. In addition, Mercer provided services to the Company for investment and benefits consulting and retirement

plan consulting, which services were approved by management. During 2022, the aggregate fees for such services were approximately

$1,294,000.

䡲 The Compensation Committee determined that Mercer is (and was, during 2022) independent and that its engagement does

not (and did not, during 2022) present any conflicts of interest that would prevent Mercer from serving as an independent

consultant to the Compensation Committee.

䡲 Mercer also determined that it was independent from management and confirmed this in a written statement delivered to the

Compensation Committee.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During 2022, the following individuals served on the Compensation Committee for all or part of the year: Messrs. Claure, Gopalan,

Illek, Kübler, Westbrook and Wilkens. Mr. Wilkens ceased to be a member of the Board and the Compensation Committee on

Risk Oversight

MANAGEMENT’S ROLE IN RISK OVERSIGHT

Management of the Company, including the Chief Executive Officer and other executive officers, is primarily responsible for managing

the risks associated with the business, operations, and financial and disclosure controls. Management conducts a quarterly enterprise-

wide risk assessment and considers financial, integration, strategic, IT, cybersecurity, technology, operational, compliance, legal/

regulatory, and reputational risks to the Company, including risks that are short-term, intermediate-term and/or long-term. In addition,

management conducts an annual fraud risk assessment and an annual compliance risk assessment, and periodically assesses future

trends in ESG oversight, practices, disclosure controls and disclosures. Periodically, the Company engages third-party experts as part

of the Company’s risk assessment, including assessment of future threats and trends, and risk mitigation processes. All enterprise

risks that are considered are prioritized based on potential impact to the Company. Risk trending is also evaluated, and management

action plans and timelines are developed and tracked to address the immediacy of the risk assessed. The results of these assessments

are considered in connection with the operational, financial, and business activities of the Company.

Management Has Established a Third-Party Risk Management Program

Management has established a centralized Third-Party Risk Management program to evaluate multiple aspects of risk related to doing

business with third parties, including, but not limited to, cybersecurity, geopolitical, privacy, financial, anti-corruption, fourth-party

risks and risks relating to foreign ownership and compliance with national security commitments.

Management Has Established an Enterprise Risk and Compliance Committee and an Information Security and Privacy Council

The Enterprise Risk and Compliance Committee oversees risk management and compliance activities as a means of bringing risk

issues to the attention of senior management. Responsibilities for risk management and compliance are distributed throughout

various functional areas of the business, and the Enterprise Risk and Compliance Committee consists of representatives of

management, the enterprise risk organization, the enterprise compliance and ethics function, leaders from these functional areas of

business and subject matter experts from across the Company. The committee is co-led by our Executive Vice President and Chief

Financial Officer and Executive Vice President and General Counsel. It regularly meets and reviews the Company’s activities in these

areas. The Enterprise Risk and Compliance Committee drives the identification, prioritization, and mitigation of the Company’s most

significant risks, enables coordinated actions across the Company, and provides input to the Chief Audit Executive’s report to the

Audit Committee and the Chief Compliance Officer’s report to the Nominating & Corporate Governance Committee.

The Information Security and Privacy Council oversees the strategic governance and prioritization of the Company’s information

security (including cybersecurity), privacy and national security initiatives to help protect information assets and safeguard our

network infrastructure for the business, the Company’s employees, and the Company’s customers. The Information Security and

Privacy Council consists of representatives of management and subject matter experts from across the Company. It is co-chaired by

our Senior Vice President and Chief Security Officer and Vice President and Chief Privacy Officer. The Information Security and

Privacy Council provides strategic direction as well as oversight and acts as an escalation point concerning critical decisions, strategy

direction, and risk acceptance and mitigation.

In addition, in the fall 2021, a new information security office, the Cyber Transformation Office, was formed under the Company’s Chief

Executive Officer, overseeing the Company’s data security organization, and tasked with elevating the Company’s cyber security

capabilities and reinforcing a security-first mindset throughout T-Mobile business and operations functions.

THE BOARD’S ROLE IN RISK OVERSIGHT

Selective Delegation of Risk Oversight to Committees

Our directors have deep experience and expertise in strategic planning and execution. Through regular and s pecial Board meetings,

the Board engages with management in robust discussions about the Company’s financial and operational performance, competitive

landscape, strategic goals, operational objectives and challenges and regulatory developments.

While the full Board has overall responsibility for risk oversight, the Board has delegated risk oversight responsibility for certain risks

to committees of the Board. On a regular basis, reports of all committee meetings are presented to the Board, and the Board

periodically conducts deep dives on key enterprise risks.

Audit Committee

The Audit Committee has primary responsibility for overseeing the Company’s various risk assessment, risk management policies, and

procedures and controls. The Audit Committee considers and discusses policies with respect to risk assessment and risk

management, including the Company’s major financial risk exposures and the steps management has taken to monitor and control

such exposures.

䡵

PROXY STATEMENT 2023

Corporate Governance at T-Mobile

To assist the Audit Committee with its risk assessment function, the Senior Vice President, Internal Audit & Risk Management, who

serves as the Chief Audit Executive, has a direct communication channel to the Audit Committee for purposes of reporting or

discussing concerns, and has regular meetings with the Audit Committee and/or its members. The Chief Audit Executive provides a

quarterly enterprise-wide risk assessment (including risks relating to cybersecurity and privacy), annual fraud risk assessment, and

SOX and Internal Audit reporting or assessments to the Audit Committee, and updates the Audit Committee on significant issues

raised by the Enterprise Risk and Compliance Committee. The Audit Committee discusses the potential impact of the Company’s risk

exposures on the Company’s business, financial results, operation and reputation. The Company’s General Counsel provides periodic

reports to the Audit Committee on the Company’s significant litigation matters.

As an integral part of the Company’s disclosure controls and procedures, the Audit Committee reviews enterprise risk assessments,

provides feedback to executive management and shares the risk assessments with the Board. The Audit Committee also has other

responsibilities with respect to the Company’s financial and accounting compliance and complaint procedures, internal audit, SOX

Compliance program and related person transactions, as more fully set out in its charter. Additionally, the Chief Compliance Officer

also has a direct communication channel to the Audit Committee f or purposes of discussing or reporting financial misconduct matters

with the Audit Committee and/or its members.

CEO Selection Committee

The CEO Selection Committee oversees risks related to the selection, appointment, hiring, firing and recall from office the Chief

Executive Officer of the Company.

Compensation Committee

The Compensation Committee has certain responsibilities with respect to succession planning and the assessment of risk in

connection with our compensation programs. The Compensation Committee periodically reviews with management an assessment of

whether risks arising from the Company’s compensation policies and practices for all employees are reasonably likely to have a

material adverse effect on the Company, as well as the means by which any potential risks may be mitigated, such as through

governance and oversight policies. The Company designs the compensation programs to encourage appropriate risk-taking while

discouraging behavior that may result in unnecessary or excessive business risk. In this regard, the following elements have been

incorporated in our compensation programs for executive officers:

• Use of multiple metrics in the annual incentive plan and use of two long-term incentive vehicles (time-based and performance-

based incentive awards) for executive officers

• Annual incentive award payouts capped at 200% of target

• Performance-based long-term incentive awards capped at 200% of target

• Emphasis on long-term and performance-based compensation

• The Compensation Committee has discretion to reduce incentive awards, as appropriate

• Alignment of interests of our executive officers with the long-term interests of our stockholders through stock ownership

guidelines that call for significant share ownership by our executive officers

• Formal clawback policy applicable to both cash and equity compensation

• Generally, long-term incentive awards vest ratably over three years or at the end of a three-year performance period

• No excessive perquisites for executive officers

Based on an assessment conducted by management consultant Willis Towers Watson, which was presented to and discussed with

the Compensation Committee, management concluded that our compensation policies and practices for all employees do not

create risks that are reasonably likely to have a material adverse effect on the Company.

Executive Committee

The Executive Committee is available to review and provide guidance to senior management regarding the Company’s strategy,

operating plans and operating performance. The Executive Committee also plays a role in helping the Board perform its risk oversight

function by considering strategic operating goals, opportunities and risks.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee oversees Board process and corporate governance-related risks, management

of compliance risks, risks related to our diversity, corporate social responsibility and sustainability practices, and risks related to the

Company’s data privacy and information security programs, including cybersecurity.

Officer also has a direct communication channel to the Nominating and Corporate Governance Committee for purposes of reporting or

discussing concerns relating to the Company’s compliance and ethics programs. Matters brought to the Nominating and Corporate

Governance Committee’s attention that could have a significant impact on the Company’s financial statements or may concern the

integrity, adequacy, and effectiveness of the Company’s accounting and financial reporting processes and internal control and

external reporting policies and procedures will be reported to the Audit Committee by the Chief Compliance Officer.

The Chief Cyber Transformation Officer, Chief Security Officer and Chief Privacy Officer provide periodic reports to the Nominating

and Corporate Governance Committee on the Company’s data privacy and information and infrastructure security programs, including

cybersecurity. The Nominating and Corporate Governance Committee discusses with management the Company’s privacy and data

security, including cybersecurity, risk exposures, policies, and practices, including the steps management has taken to detect, monitor

and control such risks. The Nominating and Corporate Governance Committee, as well as the Board, receive reports from officers with

responsibilities for the Company’s data privacy and information and infrastructure security programs, including cybersecurity.

Transaction Committee

The Transaction Committee oversees risks related to strategic transactions involving the Company and its businesses.

Director Compensation

NON-EMPLOYEE DIRECTOR COMPENSATION PROGRAM

Our “non-employee directors”—directors who are not employees of the Company or officers or employees of Deutsche Telekom or

SoftBank—are eligible to participate in the Company’s non-employee director compensation program, described below. The

Compensation Committee periodically reviews the compensation of our non-employee directors. As part of the review, the

Compensation Committee engages Mercer to assess our non-employee director compensation program in comparison to our peer

group (see “Executive Compensation—Factors Considered in Determining Executive Compensation—Executive Compensation Peer

Group” for more information on our peer group). Based on such assessment, the non-employee director compensation program is

adjusted as appropriate to ensure alignment with market practices. There were no changes to the Company’s non-employee director

compensation program in 2022.

KEY FEATURES OF OUR NON-EMPLOYEE DIRECTOR COMPENSATION PROGRAM

• A larger allocation of total director compensation to equity-based compensation rather than cash compensation

Director Nomination, Selection and Qualifications

QUALIFICATIONS AND DIVERSITY

T-Mobile understands that diversity, inclusive of gender, race and experience, is a critical attribute of a well-functioning board of

directors and a measure of sound corporate governance. T-Mobile follows its director selection guidelines as we strive to maintain a

board composed of individuals with a mix of expertise, experience, skills and backgrounds to reflect the diverse nature of the business

environment in which we operate and the customers we serve. In connection with the Sprint Combination, we adopted an Equity In

Action Plan to further advance diversity, equity and inclusion efforts across T-Mobile, including at the Board level.

Subject to Deutsche Telekom’s board designation rights, the Nominating and Corporate Governance Committee is responsible for

identifying and evaluating director nominees and recommending to the Board a slate of nominees for election at each annual meeting

of stockholders.

16 PROXY STATEMENT 2023

䡵

Corporate Governance at T-Mobile

The Nominating and Corporate Governance Committee considers, among others, the following factors:

• Professional experience, industry knowledge, skills and expertise

• Diversity in all forms, including gender, race, age, ethnic, geographic, cultural and professional backgrounds

• Leadership qualities, public company board and committee experience and non-business-related activities and experience

• High standard of personal and professional ethics, integrity and values

• Training, experience and ability at making and overseeing policy in business, government and/or education sectors

• Willingness and ability to:

• keep an open mind when considering matters affecting interests of the Company and its constituents

• devote the required time and effort to effectively fulfill the duties and responsibilities related to Board and committee

membership

• serve on the Board for multiple terms, if nominated and elected, to enable development of a deeper understanding of the

Company’s business affairs

• Willingness to refrain from engaging in activities or interests that may create a conflict of interest with a director’s

responsibilities and duties to the Company and its constituents

• Willingness to act in the best interests of the Company and its constituents and to objectively assess Board, committee and

management performances

Diversity is one of many factors under our director selection guidelines that the Nominating and Corporate Governance Committee

considers when evaluating potential director candidates. Our director selection guidelines define diversity broadly to include not just

factors such as gender and race, but also factors such as age, ethnic, geographic, cultural and professional diversity. Our director

selection guidelines mandate that the skills and backgrounds collectively represented on the Board should reflect the diverse nature of

the business environment in which the Company operates and the customers it serves. In addition, according to our director selection

guidelines, the Nominating and Corporate Governance Committee will include, and will require any outside consultant that it engages

to include, women and minority candidates in the pool from which the committee selects director candidates. Eight of our current 13

directors are women or minorities, and all of our core Board committees are chaired by a woman or diverse director.

In connection with its general responsibility to monitor and advise the Board on the size, role, function and composition of the Board,

the Nominating and Corporate Governance Committee will periodically consider whether the Board represents the overall mix of skills

and characteristics described in the director selection guidelines, including diversity and the other factors described above. Subject to

Deutsche Telekom’s board designation rights, the selection process for director candidates is intended to be flexible, and the

Nominating and Corporate Governance Committee, in the exercise of its discretion, may deviate from the selection process when

particular circumstances warrant a different approach.

The table below summarizes the key qualifications, skills, and attributes most relevant to the decision to nominate candidates to serve

on the Board. A mark indicates a specific area of focus or expertise on which the Board particularly relies. Not having a mark does not

mean the director does not possess that qualification or skill. Our director nominees’ biographies describe each director’s background

and relevant experience in more detail.

We are a celebratory, inclusive, customer-obsessed team of people united in our commitment to change our industry for the better.

Our culture begins and ends with our employees—the heart and soul of the Un-carrier. We know we are a stronger company when

every employee feels valued for who they are and equipped to constantly learn, aim high, and offer the best for our customers. This

last year we emphasized the power of coming together—sometimes in-person with teammates for the first time—and fueling our

relentless spirit to innovate, grow, and propel our business forward.

Diversity, Equity, and Inclusion

We come together as one team, made up of people with unique talents, backgrounds and perspectives, which enables us to continue

to deliver growth and profitability. Our strength comes from investing in a diverse workforce that reflects the communities and

customers we serve. It’s this diversity that fuels the Un-carrier spirit.

We have continued to increase year-over-year diversity across the company, including executive representation at the Director+ levels.

The data below provides a snapshot of our workforce, highlighting areas of progress and opportunity. We publish more detailed

workforce data in our annual Corporate Responsibility Report and EEO-1 report. We plan to continue sharing our EEO-1 workforce

data each year.

DE&I is embedded in everything we do, from hiring and development, to our award-winning culture and our Equity in Action Plan. In

2020, we launched the Equity In Action Plan, which is T-Mobile’s five-year DE&I strategic plan that outlines the values we live by, how

we invest in and provide opportunities for our employees, how we select the suppliers we do business with, and how we advocate for

our customers and communities.

Environmental, Social and Governance Practices

We continue to complete initiatives in support of our Equity In Action Plan and in other areas where we see opportunities to make a

positive impact. By the end of 2022, we completed over half of our DE&I-related Promises under the Equity In Action Plan, to ensure

DE&I remains at the center of everything we do and we are on track to achieve the remaining Promises by 2025. Some of our recent

achievements include:

• Established the T-Mobile Supplier Mentor Protege program, which focuses on providing support and opportunities for

businesses owned by members of traditionally underrepresented backgrounds (including gender, race/ethnicity, and LGBTQ+

identity).

• Launched the second year of our One Team Together Learning Journey (DE&I learning) for T-Mobile employees, focusing on

unconscious bias and making more informed, effective, and confident decisions.

• Continued to expand participation in The NextTech Diversity Program, which is designed to connect individuals of traditionally

underrepresented racial/ethnics groups with the skills, training, and opportunities to become network technicians and network

equipment drivers.

• Renewed the partnership with the Thurgood Marshall College Fund in 2022 with a $2.5 million donation to support the

Thurgood Marshall College Fund’s scholarships for students attending historically Black colleges and universities and the new

National Black Talent Bank program that helps high school graduates jumpstart their professional careers and gain access to

tailored higher education pathways.

• Created the IMPACT DE&I Award to recognize and celebrate DE&I efforts that have a long-term impact and strategic benefit on

our business, employees, customers, communities, or suppliers.

T-Mobile also has six DE&I Employee Resource Groups and four sub-affinity groups that focus on dimensions of inclusion that are

most relevant to our employees and company. Currently, we have over 40 local DE&I chapters across the nation that help spearhead

volunteer opportunities, events, and meaningful conversation with employees at a local level. Nearly 40% of our employee population

participates in one or more of the following Employee Resource Groups: Women and Allies Network, Accessibility Community at

T-Mobile, Veterans and Allies Network, Multicultural Alliance, Multigenerational Network, and PRIDE.

T-Mobile received multiple recognitions from external organizations, including a score of 100% on the Human Rights Campaign’s

Corporate Equality Index, recognition as one of the best places to work for LGBTQ+ Equality and was named Disability:IN’s Employer

of the Year.

Compensation, Wellness and Benefits

Putting people first and treating them right is core to our values and how we operate. That’s why we embed principles and practices

of equity in compensation packages (base salaries, bonuses, paid time off, etc.) from the outset while considering factors such as

market data, employee’s role and experience, job location, and performance. Our benefits program is also driven by a focus on equity

as well as employee feedback, with the aim of creating a comprehensive benefits package that supports our diverse employee base

through major life events. We attract and retain our workforce by providing a package of what we believe are exceptional benefits to

all eligible full-time and part-time employees—from frontline to executives to back-office employees—including:

• Competitive medical, dental and vision benefits

• Annual stock grants to all full-time and part-time employees and a discounted Employee Stock Purchase Program

• A 401(k) Savings Plan

• Nationwide minimum pay of at least $20 per hour to all full-time and part-time employees

• A generous paid time off program, including access to Paid Family Leave

• Family-building benefits designed to meet the diverse needs of our employees including egg and other tissue extraction and

freezing, tissue purchase, IVF and IUI, adoption, and surrogacy benefits

• LiveMagenta: a custom-branded program for employee engagement and well-being, including free access to life coaches,

financial coaches and tools for healthy living

• Access to personal health advocates offering independent guidance

• Tuition assistance for all full-time and part-time employees, including full tuition partnerships with multiple schools

• A matching program for employee donations and volunteering

Career Development, Learning and Training

Career growth and development for our employees is foundational to T-Mobile’s culture and success. We have a range of development

programs and resources designed to build a diverse group of leaders and empower employees to improve their skills and advance

their careers. Resources for employees are easily accessible on our Magenta University site, which is our one-stop shop for all things

PROXY STATEMENT 2023

Environmental, Social and Governance Practices

related to career development and learning. The online learning portal provides our employees with access to mentoring, training,

videos, books, job search and interview tips, and much more.

By strategically investing in three key areas of career development and learning, we’re developing our people now and for the future.

• Evolve skills and careers: Learn every day, champion relentless improvement, develop critical skills, explore career

possibilities, and build the career our employees want. We do this through events like our annual company-wide Day of

Learning and programs, or CareerTrax, a nine-month job rotation program for employees up through the senior manager level.

• Advance leadership expertise: Build critical leadership capabilities, enable leadership growth at all levels, and develop skills to

lead in the future. T-Mobile does this through a range of programs, including Magenta

, an award-winning leadership

development offering that invests in senior managers identified as top talent.

• Champion DE&I: Promote inclusive habits and behaviors, enhance belonging and connectedness, and advocate for equitable

opportunities. Beyond our all-employee One Team Together Learning Journey, T-Mobile also has several programs that

champion DE&I through career development, including Lead Magenta Next, which helps to develop underrepresented talent.

COMMUNITY INVESTMENT AND DIGITAL EMPOWERMENT

T-Mobile is passionate about being a n even greater force for good in wireless and the world in which we live. This means being the

best in the world at creating a connected world where everyone can thrive. We are committed to using our transformational 5G

network, resources and scale to be a force for good in our communities.

T-MOBILE FOR GOOD

Access to Connectivity and Bridging the Digital Divide

Ensuring that everyone thrives in a digital world means starting with access to fast, affordable, available, and reliable connectivity. We

have rapidly built out our network to deliver the broadest and deepest 5G experience across the country—including rural areas—while

offering more affordable options to families with limited incomes to support a more connected, digitally equitable f uture.

To further empower more Americans with the connectivity they need to navigate the digital world, we focus critical investments on

bridging the digital divide. We believe access to education is access to opportunity and no student should be left behind. That’s why

in 2020 we launched Project 10Million, our $10.7 billion, five-year commitment aimed at delivering free internet and mobile hotspots

to eligible student households. We also offer school districts free and heavily subsidized data plans as well as access to affordable

laptops and tablets. In collaboration with school districts, community partners like Big Brothers Big Sisters of America, and student

families, we’ve connected over 5.3 million students through our education initiatives and provided over $4.8 billion in products and

services through the end of 2022.

䡵

PROXY STATEMENT 2023

Environmental, Social and Governance Practices

As our network expansion continues, we are on track to cover 99% of Americans with 5G by the end of 2023 so that customers across

the nation can benefit from having access to the largest, fastest and most reliable 5G network for mobile broadband. We have also

continued to expand our High-Speed Internet service which gives important new home broadband connectivity options to millions of

households, including those in rural communities.

Understanding that affordability is a critical component to e xpanding access to connectivity, we offer Connect by T-Mobile, a low-cost

service plan to keep millions of families and individuals connected. In 2022, to provide more new customers with access to our

network and services, we also announced Price Lock, a promise for all new postpaid and high speed internet customers on eligible

rate plans that the price of their talk, text and data would stay the same unless they change it.

We also remain committed to helping America’s frontline heroes at the most critical times. Connecting Heroes is T-Mobile’s 10-year

commitment to provide free smartphone service and 5G access to state and local nonprofit first-responder agencies across the nation.

and the T-Mobile

Foundation

Our employees are at the heart of the good we do and serve as champions for their local communities. By empowering employees to

support the causes they care most about, we help to create vibrant, resilient communities. In 2012, the Company created the T-Mobile

USA Foundation (the “T-Mobile Foundation”) to support charitable activities reflecting the charitable interests of the Company and its

employees. Through the T-Mobile Foundation Magenta Match program, we match employee donations to charities of their choice and

donate ten dollars for every volunteer hour, up to $2,000 per employee per calendar year. In 2022, our employees donated $3.2 million

and volunteered over 61,000 hours in their communities.

Disaster Response

When disasters impact our customers and communities, connectivity is a crucial lifeline. We take a comprehensive approach to

disaster preparation and response. Thanks to our distributed model of warehouses around the country, we can quickly deploy supplies

and our emergency management fleet, including satellite enabled vehicles, mobile command centers, Cells on Wheels and Cells on

Light Trucks, to impacted areas. Vehicles can be almost anywhere in the U.S. within 12 hours to set up charging stations, WIFI and

provide other much-needed personal cellular supplies. We also partner closely with national weather forecasters to monitor for climate-

related emergencies. Once a storm hits, our investments in our network’s resiliency and infrastructure prove critical. In total, T-Mobile

provided $1.6 million in devices, services, and other supplies to support disaster relief efforts in 2022.

Environment – Mobilizing for a Thriving Planet

We know sustainability is important to our customers and other stakeholders, which is why we are committed to investing in initiatives

that make our business more resilient and our products and services more sustainable. This means evaluating ways we can operate

more sustainably and using our unique network, scale and resources to enable others to live, work, and connect in a more

environmentally responsible manner.

TAKING CLIMATE ACTION

An important area of focus at T-Mobile is reducing emissions across our value chain. By making meaningful changes to how we

operate and harnessing the power of our 5G technology solutions, we can play a role in the global transition to a net-zero economy.

That’s why we’re proud of our commitment to achieve net-zero emissions across our entire carbon footprint by 2040 under a target

validated by the SBTi—a U.S. wireless industry first.

Our net-zero target has been validated by SBTi using their Net-Zero Standard. As part of this goal, we have set two science-based

emissions reduction targets:

• Near-term target: Reduce absolute Scope 1, 2 and 3 GHG emissions 55% by 2030 from a 2020 base year

• Long-term target: Reduce absolute Scope 1, 2 and 3 GHG emissions 90% by 2040 from a 2020 base year

PROXY STATEMENT 2023

䡵

Environmental, Social and Governance Practices

T-Mobile’s goal is to abate our emissions to be as close to zero as possible and only use carbon offsets to address the remaining 10%

or less of emissions. To bolster this new goal, T-Mobile also signed onto The Climate Pledge, joining a cross-sector community of

companies and organizations working together to solve the challenges of cutting global carbon emissions for a sustainable future. We

plan to detail our progress and share updates to our roadmap in the Pathway to Net-Zero Report, Corporate Responsibility Report, and

CDP Climate Change disclosures, all of which we plan to publish annually.

T-Mobile continued to score at the Leadership Level and received an A- on CDP Climate Change reporting for 2022.

Sustainable Energy Management

Sustainable energy management is critical to reducing our carbon footprint and includes investing in energy efficiency measures to

conserve energy where possible and investing in renewable energy projects to account for the electricity we purchase.

We were the first and only U.S. wireless provider to achieve our goal to source renewable energy equivalent to 100% of our electricity

usage by the end of 2021. In 2022, we continued to maintain this position while exploring new renewable energy projects to further

diversify our portfolio.

This milestone is complemented by a focus on energy conservation and investments in energy efficiency. We have continued to make

progress on our energy efficiency goal to reduce energy consumption by 95% per petabyte of data traffic by 2030 (from a 2019 baseline).

Reducing Waste

Another important part of reducing our footprint includes working to responsibly manage waste and e-waste across our value chain

through our actions and commitments, and the opportunities we provide for employees and customers. T-Mobile continually seeks to

reduce operational waste generated from our business. We also helped develop the CTIA Guidelines for Wireless Device and

Accessory Packaging to provide guidance on mitigating the environmental impact from mobile wireless device and accessory

packaging. These guidelines were released in 2020 and continue to be a point of engagement with our suppliers.

T-Mobile has an internal e-waste management program to help increase the percentage of network, IT and real estate e-waste that is

reused or recycled. We empower our customers to reduce e-waste by offering options to bring in smartphone, tablet, smartwatch,

hotspot or IoT item into select stores to be upcycled or recycled for free. In 2022, T-Mobile collected 11.7 million devices for reuse,

resale, and recycling, including phones, smartwatches, tablets, hotspots, and IoT items. Our suppliers and partners that repair and

recycle these devices are required to be certified to the industry-leading R2 standard, which provides a common set of processes,

safety measures, and documentation requirements.

Governance – Doing it the Right Way

No matter how quickly or boldly we move—there is only one way to deliver—and that’s by doing things the right way—through ethical

conduct and socially and environmentally responsible business practices.

CORPORATE POLICIES AND TRAINING

Our primary policy focused on ethical business practices is our Code of Business Conduct, which establishes clear expectations for

our directors, officers and employees. It sets forth the workplace conduct standards and legal guidelines that we expect them to follow

when working on behalf of T-Mobile.

䡵

PROXY STATEMENT 2023

Environmental, Social and Governance Practices

Our Supplier Code of Conduct outlines expectations around ethical business practices for all T-Mobile suppliers. Even before suppliers

are selected, a third-party risk management process screens for anti-corruption, global sanctions, human rights, and environmental

risks.

To support our commitment to doing right by the environment and driving sustainability across our business, our Environmental Policy

outlines key areas of focus and objectives, from tackling climate change to reducing waste and promoting the efficient use of natural

resources.

The T-Mobile Human Rights Statement underscores our commitment to respecting human rights and the expectations for our

employees and business partners, as well as the mechanisms to help identify and address any potential violations.

In our Code of Business Conduct, and through our Speak-Up Policy, we encourage our employees to report a concern, a possible

violation of our policies, or to seek advice on how to implement the organization’s policies and practices for responsible business

conduct. We provide employees with tools that enable them to speak up anonymously and without fear of retaliation through our third-

party integrity line (online or by phone), by emailing our compliance & ethics team, or contacting our Chief Compliance Officer or the

Chair of the Audit Committee directly. Our Speak-Up Policy outlines how people are protected from retaliation whenever they raise or

report suspected misconduct or a potential violation of the law in good faith.

We take a continuous learning approach so that our employees have the knowledge and tools necessary to integrate the standards set

forth in our policies into how we conduct our business every day. Training takes place multiple times throughout the year and is

required of all employees and officers of the Company. This training covers topics such as data safety and privacy, anti-corruption,

health and safety, harassment and discrimination, and insider trading, and enables everyone to understand our expectations and

commitment to ethical business practices.

DATA PRIVACY & CYBERSECURITY

Our business involves the receipt, storage, and transmission of confidential information about our customers, such as sensitive

personal, account and payment card information, confidential information about our employees and suppliers, and other sensitive

information about our Company, such as our business plans, transactions, financial information, and intellectual property. T-Mobile is

committed to maintaining the trust of our customers, employees, partners, and the public by respecting the value of such confidential

information, including that personal information entrusted to us and handling such information responsibly. See disclosures under

“Corporate Governance at T-Mobile—Risk Oversight” on the management, Board and Board committees’ oversight of information

security, including cybersecurity and privacy issues.

Data Privacy

We are committed to responsible data use, including as defined by legal obligations and by industry best p ractices T-Mobile observes,

such as the Cellular Telecommunications and Internet Association (“CTIA”) Consumer Code of Conduct.

We equip our employees and key contractors with training and knowledge-based resources to help them carry out proper privacy and

security practices. This basic training is supplemented by awareness work performed through our Security and Privacy Ambassador

Network (“SPAN”), which is comprised of a team of privacy and security experts embedded throughout the Company. SPAN is

managed by T-Mobile’s data privacy team, and supported by other subject matter experts in the Company.

The Privacy Center on the T-Mobile website provides customers and employees tools to access T-Mobile’s Privacy Policies,

understand how T-Mobile uses personal data, navigate the choices we offer for control of data use and sharing, and find resources

and tips for online safety. In 2022, the site was further enhanced to make it more consumer friendly. T-Mobile also deployed a new

privacy dashboard in customer accounts that centralizes and simplifies the privacy controls and choices available.

Cybersecurity

While we, like any other company, are unfortunately not immune to criminal attacks, we continue to make substantial, multi-year

investments in strengthening our cybersecurity program. Ongoing investments include formation of a Cyber Transformation Office

under the Company’s Chief Executive Officer in the fall of 2021 to oversee the Company’s cybersecurity organization and elevate the

Company’s cybersecurity capabilities.

In 2022, the Cyber Transformation Office led internal testing and external audit of our cybersecurity policies and processes. It also

provided cybersecurity foundations training for nearly every employee and partner, and trained thousands more with advanced role-

based training. The Company also engaged in long-term collaborations with industry experts for threat intelligence, strategy and

program execution. We are accelerating our efforts against eight strategic enterprise-wide cybersecurity initiatives aimed at enhancing

our capabilities in access management, asset management, culture change, cyber defense, data security, secure development

lifecycle, third-party cyber risk and vulnerability management.

STOCKHOLDER ENGAGEMENT

T-Mobile understands the importance of frequent, consistent, and transparent communication with stockholders as part of our

commitment to strong corporate governance. Our senior management team engages extensively and regularly with stockholders,

including through one-on-one meetings, group meetings, and major industry conferences. Our investor relations team actively engages

in year-round robust dialogue in multiple ways, including p ost-earnings communications and with stockholders of all sizes on a variety

of topics, such as corporate strategy, business performance, financial results, and ESG matters. This approach allows us to maintain

meaningful two-way dialogue with a broad range of stockholders. In 2022, we met with substantially all of our top 50 active

institutional stockholders and increased our overall stockholder engagement on a year-over-year basis. To communicate broadly with

all stakeholders, we also share ESG information through our Corporate Responsibility Report, Investor Relations website, Annual

Report, Proxy Statement, and on the T-Mobile Newsroom. Working with our Corporate Secretary, our investor relations team p rovides

relevant investor feedback to our Board of Directors and senior management team.

PROXY STATEMENT 2023

PROPOSAL 2:

RATIFICATION OF THE APPOINTMENT

OF DELOITTE & TOUCHE LLP

AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2023

The Audit Committee has appointed Deloitte & Touche LLP (“Deloitte”) to serve as our independent registered public accounting firm

for the fiscal year ending December 31, 2023. Although ratification of the appointment of Deloitte by our stockholders is not required,

the Board is submitting the appointment of Deloitte to our stockholders for ratification as a matter of good corporate governance.

Changes in Certifying Accountant

On April 13, 2022, our Audit Committee dismissed PricewaterhouseCoopers LLP “(PwC”) as the Company’s independent registered

public accounting firm. The reports of PwC on the consolidated financial statements of the Company and its subsidiaries as of and for

the fiscal year ended December 31, 2021 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or

modified as to uncertainty, audit scope, or accounting principles.

During the Company’s fiscal year ended December 31, 2021, and the subsequent interim period through April 13, 2022, there were:

(i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Company and PwC on any matter of

accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to

PwC’s satisfaction, would have caused PwC to make reference thereto in their reports, and (ii) no “reportable events” within the

meaning of Item 304(a)(1)(v) of Regulation S-K.

We previously provided PwC with a copy of the above disclosures as included in our Current Report on Form 8-K filed with the SEC on

April 15, 2022, and requested PwC to furnish us with a letter addressed to the SEC stating whether PwC agreed with the statements

made by us in response to Item 304(a) of Regulation S-K and, if not, stating the respects in which it does not agree. A copy of PwC’s

letter, dated April 15, 2022, is attached as Exhibit 16.1 to that Current Report on Form 8-K, and is incorporated herein by reference.

On April 13, 2022, the Audit Committee approved the engagement of Deloitte as the Company’s independent registered public

accounting firm for the fiscal year ending December 31, 2022, effective immediately after the Company filed its Quarterly Report on

Form 10-Q for the quarterly period ended March 31, 2022 with the SEC. During the Company’s fiscal year ended December 31, 2021,

and the subsequent interim period through April 13, 2022, neither the Company nor anyone acting on its behalf consulted with

Deloitte regarding: (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of

audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided

to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to any

accounting, auditing, or financial reporting issue, (ii) any matter that was the subject of a disagreement within the meaning of Item

304(a)(1)(iv) of Regulation S-K, or (iii) any “reportable event” within the meaning of Item 304(a)(1)(v) of Regulation S-K.

We expect representatives of Deloitte to be present at the Annual Meeting. They will have an opportunity to make a statement if they

so desire and are expected to be available to respond to appropriate questions by stockholders.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF

DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC

ACCOUNTING FIRM FOR FISCAL YEAR 2023

Required Vote

The affirmative vote of a majority of the votes cast by stockholders entitled to vote at the Annual Meeting is required to approve this

proposal. If the stockholders do not ratify the appointment of Deloitte, the Audit Committee will reconsider the appointment but is

under no obligation to appoint a different independent registered public accounting firm.

THE COMPENSATION PROVIDED

TOTHECOMPANY’SNAMEDEXECUTIVEOFFICERS FOR2022

We are asking stockholders to approve an advisory, non-binding resolution (commonly referred to as a “say-on-pay” resolution) to

approve the compensation of the Company’s named executive officers as reported in this proxy statement.

We urge stockholders to read the “Compensation Discussion and Analysis” section of this proxy statement, which describes how our

executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the

Summary Compensation Table and other related compensation tables, notes and narrative, which provide detailed information on the

compensation of our named executive officers for 2022. The Board and the Compensation Committee believe that the policies and

procedures articulated in the “Compensation Discussion and Analysis” are effective in achieving our goals and that the compensation

of our named executive officers reported in this proxy statement has contributed to the Company’s recent and long-term success.

The Board has adopted a policy providing for a triennial “say-on-pay” advisory vote. In accordance with this policy and Section 14A of

the Exchange Act and as a matter of good corporate governance, we are asking stockholders to approve the following advisory

resolution at the Annual Meeting:

RESOLVED, that the stockholders of T-Mobile US, Inc. (the “Company”) approve, on an advisory basis, the compensation of the

Company’s named executive officers for 2022 as disclosed in the Compensation Discussion and Analysis, the Summary Compensation

Table and the related compensation tables, notes and narrative in the Proxy Statement for the Company’s Annual Meeting of

Stockholders.

This advisory “say-on-pay” resolution is non-binding on the Board. Although non-binding, the Board and the Compensation Committee

will review and consider the voting results when making future decisions regarding our executive compensation program. Unless the

Board modifies its policy on the frequency of future “say-on-pay” advisory votes, which it may do following the outcome of Proposal 4

(Advisory Vote on the Frequency of Future Advisory Votes to Approve the Compensation Provided to the Company’s Named Executive

Officers, for which the Board has recommended that our stockholders vote for a frequency of every three years), the next “say-on-pay”

advisory vote will be held at the 2026 annual meeting of stockholders.

, postpaid net customer

additions of 6.4 million and High Speed Internet net customer additions of 2.0 million in 2022. We ended 2022 with a record high in

total customers of 113.6 million.

Our record customer growth translated into industry-leading postpaid service revenue and cash flow growth in 2022. We ended 2022

with total service revenues of $61.3 billion, postpaid service revenues of $45.9 billion, net income of $2.6 billion, Core Adjusted

EBITDA of $26.4 billion, net cash provided by operating activities of $16.8 billion and Free Cash Flow of $7.7 billion. We realized

approximately $6.0 billion of synergies from the Sprint Combination in 2022.

We further extended our reputation for value while translating our 5G lead into overall network leadership for the first time, as noted by

multiple third parties. At the end of 2022, our 5G network covered 325 million people (98% of Americans), and our super-fast Ultra

Capacity 5G covered 263 million people nationwide.

Our stock price increased by 64.5% from April 1, 2020 (the closing date of the Sprint Combination) to December 31, 2022.

Executive Officers’ actual total compensation as reported in the 2022 Summary Compensation Table was in the form of variable

compensation (short-term and long-term incentives).

Executive Compensation

Factors Considered in Determining Executive Compensation

COMPENSATION CONSULTANT AND MANAGEMENT

The Compensation Committee sets compensation levels for our Named Executive Officers based on the individual skills, experience

and achievements of each executive officer, taking into account market analysis, input by its independent compensation consultant

(Mercer) and the compensation recommendations of our Chief Executive Officer, except with respect to his own compensation. The

Chief Executive Officer provides recommended annual compensation adjustments for the other Named Executive Officers’ base

salaries, target annual short-term incentive opportunities and target long-term incentive opportunities. The Compensation Committee

believes that input from both its independent compensation consultant and our Chief Executive Officer provides useful information

and points of view to assist the Compensation Committee in determining appropriate compensation.

The Compensation Committee has assessed the independence of Mercer pursuant to the rules prescribed by the SEC and has

concluded that no conflict of interest existed in 2022 or currently exists that would prevent Mercer from serving as an independent

consultant to the Compensation Committee.

APPROACH TO COMPENSATION BENCHMARKING

We believe a competitive total compensation package is necessary to attract and retain an executive management team with the

appropriate abilities and experience required to lead the Company and execute on our strategic business plan. We use comparative

executive officer compensation data publicly disclosed by a peer group of public companies in addition to compensation survey data

with respect to that peer group to evaluate the competitiveness of our executive officer compensation and to guide the compensation

for newly hired and promoted executive officers. In analyzing this information, we compare our executive compensation program as a

whole to the programs of our peer group and compare the pay of our individual executives to that of the executive officers of our peer

group if we believe the positions are sufficiently similar to make meaningful comparisons. We do not target a specific percentile in the

range of comparative data for each individual or for each component of compensation, except as provided below for Mr. Sievert. In

determining the amount of base salary, the target annual short-term incentive award value and the target annual long-term incentive

award value for each Named Executive Officer, we review the comparative compensation data and consider each executive’s level of

responsibility, prior experience, past job performance, internal comparators, contribution to the Company’s success and results

achieved. The Compensation Committee exercises its business judgment and discretion and does not apply formulas or assign these

factors specific mathematical weights, except as provided below for Mr. Sievert.

During 2022, Mr. Sievert’s employment agreement with the Company, which was entered into in November 2019 (as amended, the

“2019 Sievert Employment Agreement”) and which, as discussed below, was amended and restated in March 2023, required us to

review the compensation of Chief Executive Officers in our peer group for purposes of determining certain components of Mr. Sievert’s

2022 compensation. The 2019 Sievert Employment Agreement provided that effective January 1, 2022, Mr. Sievert’s base salary would

be increased to the greater of (i) $1,600,000 and (ii) the then-current median annual base salary for Chief Executive Officers in our

peer group. In accordance with this provision, the Company, along with the Compensation Committee and their consultant

determined that the median annual base salary for Chief Executive Officers in our peer group as of January 1, 2022 was $1,667,506,

and, accordingly, increased Mr. Sievert’s base salary to such amount on January 1, 2022. Additionally, the 2019 Sievert Employment

Agreement provided that effective January 1, 2022, Mr. Sievert’s annual long-term incentive (“LTI”) target value would increase to the

greater of (i) $15,000,000 and (ii) the then-current median target grant-date value of annual equity incentive awards for Chief Executive

Officers in our peer group. In accordance with this provision, the Company, along with the Compensation Committee and their

consultant determined that the median target grant-date value for Chief Executive Officers in our peer group as of January 1, 2022 was

$16,166,667, and, as a result, Mr. Sievert’s annual LTI awards granted in 2022 had a target grant-date value of $16,166,667. The 2019

Sievert Employment Agreement also provided that 60% of the time-based restricted stock units (“RSUs”) granted to him as annual LTI

awards during 2022 would have a total vesting schedule length no longer than the median total vesting schedule length of annual

time-based equity incentive awards for Chief Executive Officers in our peer group at the time such RSUs are granted. In accordance

with this provision, the Company, along with the Compensation Committee and their consultant, determined that the median total

vesting schedule length of annual time-based equity incentive awards for Chief Executive Officers in our peer group was three years,

which is the same as the three-year vesting schedule that generally applies to time-based RSUs granted to our employees.

EXECUTIVE COMPENSATION PEER GROUP

We select our peer group based on similarity to us in terms of relative size of revenue and market capitalization, industry and the

ability to compete with us for talent at the executive officer level. The Compensation Committee reviews the Company’s peer group on

an annual basis.

Our 2022 peer group was the same as our 2021 peer group. This peer group, established effective as of January 1, 2021, was used to

set executive compensation for 2022. The following chart shows T-Mobile’s 2022 peer group of 14 companies and each such

company’s revenue for its most recent fiscal year and market capitalization as of December 31, 2022.

ANALYSIS OF EXECUTIVE OFFICER COMPENSATION

The key components of our annual target total compensation package for executive officers are base salary, annual cash-based short-

term incentive awards, and long-term equity incentive awards, including PRSUs and RSUs.

TARGET TOTAL DIRECT COMPENSATION

The Compensation Committee reviews the compensation of the Named Executive Officers based on a market analysis prepared by

management in partnership with the Compensation Committee’s independent compensation consultant. Based on the Compensation

Committee’s assessment of each Named Executive Officer in relation to peer proxy and survey market data related to such peer group,

the executive officer’s contributions to the Company’s ongoing strategy, and, for Mr. Sievert, the peer group comparative provisions in

the 2019 Sievert Employment Agreement, the Compensation Committee increased the total target compensation for the Named

Executive Officers for 2022, including an increase to one or more of the following components: base salary, target annual short-term

incentive opportunity and target annual long-term incentive opportunity.

ANNUAL BASE SALARIES

Base salary is designed to provide a competitive fixed component of income. Base salaries for our Named Executive Officers are set

by the Compensation Committee, with assistance from the Compensation Committee’s independent compensation consultant, after

consideration of various factors including individual performance, executive experience and skill set, retention considerations, and

market data. In particular, the Compensation Committee focuses on how base salary levels may impact the market competitiveness of

an executive’s total compensation opportunity and, for Mr. Sievert, comparative data from Chief Executive Officers in our peer group in

accordance with the 2019 Sievert Employment Agreement. See further discussion under “— Factors Considered in Determining

Executive Compensation” above.

ANNUAL SHORT-TERM INCENTIVES

Our executive officers are eligible for annual cash-based short-term incentive awards under the 2013 T-Mobile Omnibus Incentive Plan,

as amended (the “2013 Plan”). The Compensation Committee sets the annual target value of each executive’s short-term incentive

award opportunity as a percentage of the executive’s base salary. The final award is based on the applicable executive’s eligible base

earnings for the performance period. Generally, award opportunities for each metric evaluated under the 2013 Plan are established at

threshold, target and maximum levels. The maximum level for each metric is capped at 200% of target, and as a result, the overall

potential amount that could be earned is capped at 200% of target.

The 2022 short-term incentive plan (the “2022 STIP”) awards for our executive officers, including the Named Executive Officers, were

based entirely on Company performance, which was measured by: US GAAP Service Revenue, Total Net Additions, Core Adjusted

EBITDA, and Free Cash Flow. These measures (the relative weightings of which are set forth in the table below) were aligned with the

operational objectives of the Company’s business. Attainment of the threshold performance level (representing attainment of 25% of

the target performance level) for at least one of the performance metrics was required in order for the executives to receive any

payment under the 2022 STIP. If none of the performance thresholds had been achieved during 2022, no awards would have been

paid.

Executive Compensation

LONG-TERM INCENTIVES

We grant our executive officers long-term incentive compensation in the form of PRSUs and RSUs under the 2013 Plan and the Sprint

Corporation Amended and Restated 2015 Omnibus Incentive Plan (the “2015 Plan”). For PRSUs granted in 2022, 65% are measured

based on our relative total shareholder return (“RTSR”) over a three-year performance period and 35% are measured based on our free

cash flow (“FCF”) over a three-year performance period. We believe these to be appropriate performance measures. RTSR inherently

reflects relevant financial and operational results as share price is a reflection of our current and expected future performance and

directly links a significant portion of executive officer compensation to stockholder value creation. FCF provides increased focus on

our ability to generate cash from operations and our core long-term financial outcomes that are most beneficial to the Company and its

stockholders. Earned RTSR PRSUs are settled in shares of our common stock, and the FCF PRSUs are settled in cash (with the

amount of cash paid based on the value of our common stock).

LONG-TERM INCENTIVE AWARDS GRANTED IN 2022

On February 15, 2022, we granted annual long-term incentive awards to our Named Executive Officers. Each such Named Executive

Officer received half of the aggregate value of their 2022 long-term incentive awards in the form of PRSUs and half of such value in the

form of RSUs. We believe this mix emphasizes long-term Company performance as well as the retention and engagement of the

Named Executive Officers. RSU awards for 2022 generally vest annually in three equal tranches beginning February 15, 2023, subject

to the Named Executive Officer’s continued service through the applicable vesting date. The annual PRSU awards for 2022 generally

cliff vest at the conclusion of the three-year performance period ending on the third anniversary of the grant date, subject to the

Named Executive Officer’s continued service through the vesting date and based on the level of RTSR or FCF performance (as

applicable) attained during the performance period as certified by the Section 16 Subcommittee of the Compensation Committee.

FCF PRSUs

For the PRSU awards eligible to vest based on FCF performance, PRSU achievement can range from 0% to 200% of target based on

absolute FCF performance, and payouts are determined by multiplying the target number of PRSUs by an Adjustment Percentage as

set forth in the following table. No payout will be made if performance is attained below threshold performance. For FCF performance

between the Threshold, Target, and Maximum values, the Adjustment Percentage shall be interpolated on a linear basis (except for a

RTSR PRSUs

For the PRSU awards eligible to vest based on RTSR, PRSU achievement can range from 0% to 200% of target based on our total

stockholder return relative to the total stockholder return of our peer group, and payouts are determined by multiplying the target

number of PRSUs by an Adjustment Percentage based on the RTSR percentile performance of the Company, as set forth in the

following table. For RTSR performance between the Threshold, Target, and Maximum values, the Adjustment Percentage shall be

interpolated on a linear basis. No payout will be made if performance is attained below the 25

percentile.

RTSR for the 2022 PRSU awards is generally measured against the following peer group, consisting of 14 companies: AT&T, Charter

Communications, Cisco Systems, Comcast, Dish Network, Intel, International Business Machines, Liberty Global, Lumen

Technologies, Microsoft, Oracle, Qualcomm, The Walt Disney Company and Verizon Communications. Under the terms of the award, if

one or more members of the peer group cease to be a publicly traded entity during the performance period, then that company will be

removed from the peer group; however, unless otherwise determined by our Compensation Committee, any member of the peer group

that ceases to be a publicly traded entity during the performance period due to bankruptcy or insolvency (as determined by the

Compensation Committee) will not be removed from the peer group. No additional companies will be added to the peer group for

purposes of determining any earned PRSU awards.

PERFORMANCE-BASED LONG-TERM INCENTIVE AWARDS VESTED IN 2022

The annual PRSUs (which vested based on the level of RTSR as of the conclusion of the applicable performance period and continued

service through the vesting date) granted in 2019 to each of the Named Executive Officers who were then-employed by us had a three-

year performance period that ended on February 15, 2022. Based on the Company’s RTSR at the end of the performance period,

121% of the target award was earned for each Named Executive Officer. The number of 2019 PRSUs earned by each such Named

Executive Officer and paid in 2022 is set forth in the table below.

While Mr. Draper was not employed by us in 2019 and, accordingly, did not receive an award of annual PRSUs in 2019 that vested in

2022, a special PRSU award was granted to him on April 1, 2020 in connection with the closing of the Sprint Combination. Such

special PRSU award cliff-vested on A pril 1, 2022, the second anniversary of the grant date, and was earned with an adjustment

percentage of 104% based on RTSR performance during a two-year performance period that ended on April 1, 2022. The number of

PERQUISITES

We generally do not provide perquisites to any executive officer, including the Named E xecutive Officers, beyond what all other

employees may be eligible to receive. In 2022, we provided personal security for Mr. Sievert due to the range of security issues

encountered by Chief Executive Officers of large public companies, particularly with respect to high-profile Chief Executive Officers

such as Mr. Sievert. For 2022, we paid $79,082 toward Mr. Sievert’s personal security. We also reimbursed Mr. Nelson for relocation

expenses totaling $63,272.

COMPREHENSIVE BENEFITS PACKAGE

We provide a competitive benefits package to all full-time employees, including the Named Executive Officers, that includes health and

welfare benefits, such as medical, dental, vision care, disability insurance, life insurance benefits and a 401(k) savings plan (with an

employer match up to 4%). We provide a non-qualified deferred compensation plan under which eligible participants may defer up to

75% of their base salary and 100% of their annual short-term incentive and annual RSUs. We do not provide any employer matching

or discretionary allocations under the non-qualified deferred compensation plan.

PROXY STATEMENT 2023

Executive Compensation

SEVERANCE AND CHANGE-IN-CONTROL BENEFITS

We provide severance pay and other termination benefits to eligible executive officers, including the Named Executive Officers, whose

employment is terminated, including due to corporate restructuring, and, in some cases, due to involuntary termination by us without

cause, due to our non-renewal of the executive’s employment term, due to the executive’s retirement, due to the executive’s death or

disability or due to the voluntary termination by the executive for good reason. We believe that these severance benefits provide our

executive officers, including our Named Executive Officers, with security of transition income and benefit replacement, thus allowing

such executive officers to focus on our prospective business priorities that create value for our stockholders. We believe the level of

severance and termination benefits provided is consistent with the practices of our peer group and is necessary to attract and retain

key employees. These benefits are provided pursuant to our Severance Guidelines, Executive Continuity Plan, the 2013 Plan, the 2015

Plan and incentive award agreements as well as written employment agreements, term sheets and/or letter agreements, as applicable,

that we have entered into with each of our Named Executive Officers. These arrangements do not include any gross up for excise

taxes imposed as a result of severance or other payments that are deemed made in connection with a change in control. The potential

payments and benefits available under these arrangements are discussed further under “— Potential Payments upon Termination or in

Connection with a Change in Control.”

Other Matters

TAX AND ACCOUNTING CONSIDERATIONS

Section 162(m) of the Code. Internal Revenue Code (“Code”) Section 162(m) generally disallows an income tax deduction to public

companies for annual compensation in excess of $1 million paid to the chief executive officer and other “covered employees.” While

we may take into account deductibility of compensation when making compensation decisions, we believe that maintaining the

discretion to evaluate the performance of our executive officers through the use of performance-based compensation is an important

part of our responsibilities and benefits our stockholders, even if it may be non-deductible under Code Section 162(m). Accordingly,

the Compensation Committee retains the discretion and flexibility to design and administer compensation programs that are in the

best interests of the Company and its stockholders.

Section 280G of the Code. Code Section 280G disallows a tax deduction with respect to excess parachute payments to certain

executives of companies which undergo a change in control. In addition, Code Section 4999 imposes a 20% excise tax on the

individual with respect to the excess parachute payment. Parachute payments are compensation linked to or triggered by a change in

control and may include, but are not limited to, bonus payments, severance payments, certain fringe benefits, and payments and

acceleration of vesting from long-term incentive plans including RSUs, PRSUs and other equity-based compensation. Excess

parachute payments are parachute payments that exceed a threshold determined under Code Section 280G based on the executive’s

prior compensation. As discussed above, we do not provide tax gross-ups on income attributable to severance or other payments that

are deemed made in connection with a change in control.

Section 409A of the Code. Code Section 409A requires that “nonqualified deferred compensation” be deferred and paid under plans

or arrangements that satisfy the requirements of the statute with respect to the timing of deferral e lections, timing of payments and

certain other matters. Failure to satisfy these requirements can expose employees and directors to accelerated income tax liabilities,

substantial additional taxes and interest on their vested compensation under such plans. Accordingly, it is our intention to design and

administer our compensation and benefit plans and arrangements for all of our employees and directors, including our Named

Executive Officers, so that they are either exempt from, or satisfy the requirements of, Code Section 409A.

Accounting for Stock-Based Compensation. We follow Financial Accounting Standards Board Accounting Standards Codification

Topic 718, or ASC Topic 718, for stock-based compensation awards. ASC Topic 718 requires companies to calculate the grant-date

“fair value” of their stock-based awards using a variety of assumptions. ASC Topic 718 also requires companies to recognize the

compensation cost of their stock-based awards in their income statements over the period that an employee is required to render

service in exchange for the award. Grants of PRSUs, RSUs and other equity-based awards under equity incentive award plans have

been and will be accounted for under ASC Topic 718. We expect that we will regularly consider the accounting implications of

significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and

programs. As accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity

awards with our overall executive compensation philosophy and objectives. For further information on our accounting for our stock-

based compensation awards, refer to our Annual Report on Form 10-K for the year ended December 31, 2022.

SECURITIES TRADING POLICY

Our policy on securities trading prohibits our directors, officers and designated employees from trading in our securities during certain

quarterly and event-specific blackout periods. The policy prohibits our directors, officers and designated employees from trading in

options with respect to our securities (including puts, calls and other derivative securities) on an exchange or in any other organized

market, or otherwise engaging in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market

PROXY STATEMENT 2023

䡵

Executive Compensation

value of our equity securities. The policy also prohibits short sales of our securities, holding our securities in a margin account or

pledging our securities as collateral for a loan. Mr. Claure, one of our directors, holds 2,034,791 shares of our common stock that are

pledged to secure a line of credit with an unrelated third-party bank. This pledge pre-dated the Sprint Combination, and Mr. Claure

has committed to unwind the pledge by December 31, 2024.

CLAWBACK PROVISIONS

In 2014, the Compensation Committee adopted a policy of recoupment of compensation in certain circumstances. The policy provides

that in the event the Company issues a restatement of its financial statements due to its material noncompliance with financial

reporting requirements under U.S. securities laws, the Company will, to the extent permitted by governing law, require reimbursement

from current and former executive officers for excess incentive compensation received at any time during the three-year period

preceding the date on which the Company is required to prepare the accounting restatement if a lower payment would have occurred

based on the restated results, regardless of whether the executive officer engaged in misconduct or otherwise caused or contributed

to the requirement for the restatement. The policy is administered by the Section 16 Subcommittee, which has the sole discretion to

seek recovery from an executive officer and may consider whether seeking recovery would be in the best interests of the Company,

including the costs and benefits of seeking recovery and whether doing so may prejudice the interests of the Company, including in

any related proceeding or investigation. All awards granted under our equity plans are subject to the requirements of Section 954 of

the Dodd-Frank Act regarding the recovery of erroneously awarded compensation as well as any implementing rules and regulations

under the Dodd-Frank Act, any policies adopted by the Company to implement such requirement, and any other compensation

recovery policies that may be adopted from time to time by the Company.

In light of the rules recently issued by the SEC regarding clawback policies, we expect to adopt a new or revised clawback policy

following NASDAQ’s adoption of its relevant clawback listing standards.

STOCK OWNERSHIP GUIDELINES

Under our stock ownership guidelines, the Chief Executive

Officer and all executive officers reporting to the Chief E xecutive

Officer are expected to acquire and maintain ownership of

shares of common stock equal in value to a specified multiple of

the executive officer’s base salary measured as of

September 30

of each year.

Position

Ownership

Requirement

Chief Executive Officer 5x base salary

Executive Officers reporting to the CEO 3x base salary

Each executive officer is expected to meet the ownership guidelines within five years from the later of (i) the date we adopted the

guidelines and (ii) the date on which he or she became an executive officer, and is expected to retain at least 50% of the net shares of

common stock acquired through our equity compensation plans until the ownership thresholds are met.

As of December 31, 2022, our Chief E xecutive Officer and each of the other Named Executive Officers who were then executive

officers of ours were in compliance with our stock ownership guidelines.

BROAD-BASED STOCK OWNERSHIP

WE BELIEVE THAT ALL EMPLOYEES SHOULD HAVE A STAKE IN THE

COMPANY’S PERFORMANCE. ACCORDINGLY, WE UTILIZE A

COMPANY-WIDE ANNUAL EQUITY AWARD PROGRAM.

We grant RSUs to all eligible full-time and part-time employees each year. Depending on the employee’s career band, such RSUs

become shares of T-Mobile stock following a two- or three- year vesting period, with a portion vesting each year. In addition, we

adopted an Employee Stock Purchase Plan (the “2014 ESPP”) in 2014 to provide employees with a cost-effective vehicle to purchase

stock.

EQUITY GRANTING PRACTICES

The Compensation Committee has adopted an equity grant policy pursuant to which the Compensation Committee (or the Section 16

Subcommittee) may approve annual grants to executive officers and other members of the executive leadership team at a specified

time each year. In addition to the annual grants, equity awards may be granted on a quarterly basis to new hires. We may also grant

supplemental equity awards from time to time to retain high-performing leaders, reward exceptional performance or recognize

expanded responsibility. The Compensation Committee has delegated authority to the Company’s Executive Vice President and Chief

People Officer, subject to certain terms and limitations as established by the Compensation Committee, to grant awards to employees

who are not Section 16 officers.

RESULTS OF STOCKHOLDER ADVISORY APPROVAL OF NAMED EXECUTIVE OFFICER COMPENSATION

At the 2020 annual meeting of stockholders, stockholders were asked to approve, on an advisory basis, the Named Executive Officer

compensation for 2019 as reported in the proxy statement. This say-on-pay proposal was approved by approximately 82% of the shares

present and entitled to vote, and the Compensation Committee believes this affirms our stockholders’ strong support of our executive

compensation program. Generally, the feedback from proxy advisors that did not support our 2019 say-on-pay proposal was related to

compensation and certain one-time long-term incentive awards granted to our former Chief Financial Officer to encourage his

continued retention through July 1, 2020. As these awards represented a singular compensation event to ensure leadership continuity

for our Company, rather than an ongoing aspect of our executive compensation program, our Compensation Committee did not

believe that significant changes to the Company’s executive compensation program were warranted.

Accordingly, while the Compensation Committee considered the results of the 2020 advisory vote along with stockholder input and

other factors discussed in this Compensation Discussion and Analysis, it concluded that no changes to our compensation policies and

practices were warranted in response to the stockholder advisory vote and has continued to refine our executive compensation

program for 2022 as a demonstration of its attention to corporate governance and its emphasis on the link between pay and

performance. The Board has previously determined to hold advisory say-on-pay votes every three years. Accordingly, we are asking

stockholders to approve an advisory say-on-pay resolution on the Company’s executive compensation as reported in this proxy

statement in connection with this Annual Meeting.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with Company management.

Based on such review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation

Executive Compensation

2019 Employment Agreement with Mr. Sievert. During 2022, the Company was party to the 2019 Sievert Employment Agreement,

pursuant to which Mr. Sievert served as our President and Chief Executive Officer. The 2019 Sievert Employment Agreement provided

for an initial employment term through April 1, 2023 (the third anniversary of the date on which Mr. Sievert became our Chief

Executive Officer), subject to automatic one-year extensions thereafter (unless either party provides notice of non-renewal).

Pursuant to the 2019 Sievert Employment Agreement, Mr. Sievert was entitled to (i) an annual base salary that, during 2022, was equal

to $1,667,506, which amount represents the greater of (x) $1,600,000 and (y) the then-current median annual base salary for Chief

Executive Officers in our then-current peer group; (ii) an annual short-term incentive award targeted at 250% of base salary (with a

maximum award equal to 200% of target); and (iii) employee benefits to the same extent and on the same terms as such benefits are

provided generally to other senior executives.

In addition, pursuant to the 2019 Sievert Employment Agreement, Mr. Sievert was entitled to annual LTI awards with, for 2022, a target

grant-date value of no less than $16,166,667, which represents the greater of (x) $15,000,000 and (y) the then-current median target

grant-date value of annual equity incentive awards for Chief Executive Officers in our peer group. Mr. Sievert’s annual LTI awards were

allocated as follows: 50% of such value was granted in the form of PRSUs and the remaining 50% of such value was granted in the

form of RSUs. With respect to 60% of the total RSUs granted to Mr. Sievert a s annual LTI awards during calendar year 2022

(representing 30% of the total target grant-date value for each such year), the total length of the vesting schedule of such RSUs was

no longer than the length of the median total length of the vesting schedules of annual time-based equity incentive awards for Chief

Executive Officers in our then-current peer group at the time of grant.

In February 2023, we amended Mr. Sievert’s then-outstanding awards of PRSUs and RSUs scheduled to vest in February and March

2023 such that the PRSUs and RSUs that vested during such months would be settled in cash rather than shares of our common

stock.

2023 Amended and Restated Employment Agreement with Mr. Sievert. In March 2023, the Company entered into an Amended and

Restated Employment Agreement with Mr. Sievert (the “A & R Sievert Employment Agreement”), which amended and restated in its

entirety the 2019 Sievert Employment Agreement. The A & R Sievert Employment Agreement provides for an employment term

continuing through April 1, 2028, subject to automatic one-year extensions thereafter (unless at least 90 days’ p rior notice of non-

renewal is given by either party).

Pursuant to the A & R Sievert Employment Agreement, Mr. Sievert is entitled to (i) an annual base salary initially equal to $1,750,000,

effective as of January 1, 2023, which will automatically increase to (a) effective January 1,2024, the greater of (x) $1,850,000 or (y) the

then-current median annual base salary for Chief Executive Officers in our then-current peer group, (b) effective January 1, 2025, the

greater of (x) $1,900,000 or (y) the then-current median annual base salary for Chief Executive Officers in our peer group, and (c)

effective each of January 1, 2026 and January 1, 2027, the greater of (x) $2,000,000 or (y) the then-current median annual base salary

for Chief Executive Officers in our peer group; (ii) an annual short-term cash incentive targeted at no less than 250% of his base salary

(with a maximum award equal to 200% of target); and (iii) employee benefits to the same extent and on the same terms as such

benefits are provided generally to other senior executives.

In addition, pursuant to the A & R Sievert Employment Agreement, commencing with calendar year 2023, Mr. Sievert will be entitled to

LTI awards with an annual target grant-date value that is no less than $18,500,000, which will be allocated as follows: 50% of such

value will be granted in the form of PRSUs and the remaining 50% of such value will be granted in the form of RSUs. Mr. Sievert’s

annual target grant-date value for LTI awards will automatically increase to (i) for LTI awards granted during calendar year 2024, the

greater of (x) $19,000,000, (y) the 60th percentile of the aggregate target grant-date value of annual equity incentive awards for Chief

Executive Officers in our peer group, or (z) the annual target grant-date value for LTI awards for the immediately preceding calendar

year; and (ii) for LTI grants made during calendar years 2025, 2026, 2027 and 2028, the greater of (x) $19,000,000, (y) the 65th

percentile of the aggregate target grant-date value of annual equity incentive awards for Chief Executive Officers in our peer group,

and (z) the annual target grant-date value for LTI awards in effect for the applicable prior calendar year. The A & R Sievert Employment

Agreement continues to provide that with respect to 60% of the total RSUs granted to Mr. Sievert as annual LTI awards during each of

calendar years 2023 through 2028 (representing 30% of the total target grant-date value for each such year), the total length of the

vesting schedule of such RSUs will be no longer than the length of the median total length of the vesting schedules of annual time-

based equity incentive awards for Chief Executive Officers in our peer group at the time of grant.

Pursuant to the A & R Sievert Employment Agreement, on April 1, 2023, Mr. Sievert was granted a one-time award of PRSUs (the

“Special PRSUs”) under the 2013 Plan, with respect to a target number of shares of our common stock equal to the quotient of

$10,000,000 divided by the average closing price of our common stock over the thirty calendar day period ending five days before the

grant date. The Special PRSUs will cliff-vest on the second anniversary of the grant date, based on our total shareholder return relative

to our peer group during the applicable performance period and subject to Mr. Sievert’s continued employment through such date.

Term Sheet with Mr. Ray. During 2022, the Company was party to a compensation term sheet with Mr. Ray (the “Ray Term Sheet”).

Pursuant to the Ray Term Sheet, Mr. Ray serves as our President, Technology. The current term of the Ray Term Sheet will end on

November 15, 2023, subject to automatic one-year extensions (unless either party provides notice of non-renewal).

during the applicable calendar year, and (iv) employee benefits to the same extent and on the same terms as such benefits are

provided generally to other similarly-situated executives.

8 Calculated based on the number of PRSUs (except for the 2022 FCF PRSUs which are disclosed at target) that may be earned upon achievement of the maximum performance level or

number of time-based RSUs, as applicable, multiplied by the closing price of our common stock on December 30, 2022 of $140.00 per share. In calculating the number of PRSUs and their

value, we are required by SEC rules to compare the Company’s performance through 2022 under each outstanding PRSU grant against the threshold, target, and maximum performance

levels for the grant and report in this column the applicable potential payout amount. If the performance is between levels, we are required to report the potential payout at the next highest

level. For example, if the previous fiscal year’s performance exceeded target, even if it is by a small amount and even if it is highly unlikely that we will pay the maximum amount, we are

required by SEC rules to report the awards using the maximum potential payouts.

1 The amount listed in this column for Mr. Nelson was reported in the Summary Compensation Table for 2022.

All of the Named Executive Officers are eligible to participate in the Company’s non-qualified deferred compensation plan (the

“Deferred Compensation Plan”). However, only Messrs. Ray and Nelson have elected to do so. Under the terms of the Deferred

Compensation Plan, participants are eligible to defer up to 75% of their base salary, 100% of their annual incentive compensation and

100% of annual RSU awards. All amounts attributable to participant deferrals under the Deferred Compensation Plan are fully vested

at all times. We did not provide any employer matching or discretionary allocations under the Deferred Compensation Plan for 2022.

Participants choose how their deferrals (and their account balances) will be allocated among the national investment funds available

under the Deferred Compensation Plan. For 2022, there were 18 funds for deferral of base salary and incentive compensation, which

did not include a Company stock fund. Any deferred RSUs would be credited to a Company stock fund.

PROXY STATEMENT 2023

䡵

Executive Compensation

A participant’s account balance under the Deferred Compensation Plan will be distributed in a lump-sum when the participant

terminates employment, unless termination is due to retirement or disability, in which case the participant can elect annual

installments over two to 15 years. For this purpose, “retirement” means termination of employment on or after either (i) the date on

which the sum of the participant’s age and years of service equals 65 or (ii) the date on which the participant completes ten years of

service. Participants may also elect to have amounts attributable to their deferrals for a particular year distributed (or commence to be

distributed) as of a specified date in a lump sum or in annual installments over two to five years, even if they are still employed by the

Company on that date. Generally, the specified date for base salary and incentive compensation distribution may not be earlier than

the first day of the second year beginning after the year in which such amounts are deferred and for RSUs may not be earlier than the

first day of the fourth year beginning after the year in which such amounts are deferred.

If a participant’s employment with the Company terminates prior to the in-service distribution date specified by the participant or while

in-service distribution installment payments are being made, then any portions of the participant’s account balances that are subject

to specified distribution date elections will be distributed upon termination of employment, as described above.

If a participant dies before his or her entire interest under the Deferred Compensation Plan has been distributed, his or her remaining

interest will be distributed in a lump sum to his or her beneficiary.

If a participant’s employment terminates within 24 months following a change in control (as defined in the 2013 Plan), then all

amounts credited to his or her accounts under the Deferred Compensation Plan will be paid to the participant in a lump sum within

90 days after such termination. Similarly, if a change in control occurs after a participant retires or becomes disabled, any

undistributed amounts remaining in such participant’s accounts under the Deferred Compensation Plan will be distributed in a lump

sum within 90 days after the change in control. N otwithstanding the foregoing, if a participant is a “specified employee” for purposes

of Code Section 409A at the time his or her employment with the Company terminates, then distributions on account of termination of

employment will not be made (or commence to be made) prior to the earlier of the participant’s death or the six-month anniversary of

the participant’s termination of employment. Each of the Named Executive Officers is a specified employee for this purpose.

Distributions are made in cash or stock, as applicable.

The Deferred Compensation Plan is an unfunded plan for tax purposes and for purposes of the Employee Retirement Income Security

Act of 1974, as amended. We have established a “rabbi trust” to satisfy our obligations under the Deferred Compensation Plan.

POTENTIAL PAYMENTS UPON TERMINATION OR IN CONNECTION WITH A CHANGE IN CONTROL

The following discussion describes and quantifies the estimated amount of potential payments and benefits that would be provided to

each of our Named Executive Officers under the Company’s compensation plans and agreements in the event of a termination of

employment and/or change in control of the Company (other than for Mr. Draper, whose employment with the Company ended on

April 2, 2022 and whose severance and termination payments and benefits are described below under “—Separation Payments and

Benefits to Mr. Draper”).

Our Named Executive Officers are subject to covenants regarding protection of confidential information, a non-compete and certain

other restrictive covenants regarding solicitation of employees or customers for a period through one year (or, in certain cases,

eighteen months) after termination of employment. For Mr. Sievert, this period is two years after termination of employment.

Termination Due to Death or Disability

Upon a termination of the applicable executive’s employment due to death or disability, each Named Executive Officer is entitled to

receive (i) an unpaid annual short-incentive award from the preceding fiscal year (if any); and (ii) a target annual short-term incentive

award for the current fiscal year (or, for Mr. Sievert pursuant to the 2019 Sievert Employment Agreement, the greater of a target annual

Executive Severance Benefit Guidelines

Under the Severance Guidelines, which covered all Named E xecutive Officers during 2022 (other than Mr. Sievert), if, as a result of a

corporate restructuring or business combination, a Named Executive Officer is terminated or resigns after being offered a new position

that would: (i) result in a greater than 5% reduction in total cash compensation, (ii) require a move to a work location more than 50

miles from the executive’s current work location, or (iii) significantly reduce their duties and responsibilities (including such a change

to their existing position), then, in any such case, we will consider providing the applicable executive with the Severance Guideline

Benefits. Any cash severance paid under the Severance Guidelines will be reduced by any cash severance payments payable pursuant

to any other severance plans or agreements (including amounts payable under the applicable executive’s employment arrangement

and/or the Executive Continuity Plan (as applicable)).

2022 STIP

Under our 2022 STIP, which covered all Named Executive Officers during 2022, if a change in control occurs and, on or before the

first anniversary of the change in control, either the executive’s employment is terminated by us without cause or the executive resigns

for good reason, the executive’s annual STI award will become immediately earned and vested as of the date of termination based on

the greater of target or actual performance as of the last trading day prior to the change in control or another specified date if

determined by the Compensation Committee to be necessary or appropriate based on the applicable performance goal.

“Best Pay” Provisions

The employment arrangements for Messrs. Sievert, Ray and Nelson and our Executive Continuity Plan include “best pay” provisions

under Code Section 280G, pursuant to which any “parachute payments” that become payable to the applicable executive will either

be paid in full or reduced so that such payments are not subject to the excise tax under Code Section 4999, whichever results in the

better after-tax treatment to the executive.

Change in Control (No Termination)

Pursuant to the 2013 Plan, the 2015 Plan and award agreements thereunder, in the event of a change in control of the Company in

which outstanding awards are not assumed, converted or replaced by the resulting entity, (i) all time-based LTI awards will become

vested, (ii) all performance-based LTI awards will be deemed to be satisfied and paid at the greater of target or actual performance as

of the last trading day prior to the change in control prorated up to and including the date of the change in control, and (iii) all annual

short-term incentive awards will be paid at the greater of target or actual performance as of the last trading day prior to the change in

control prorated up to and including the date of the change in control.

pro-rated short-term incentive award for 2022, based on actual performance through December 31, 2022 (in the amount of $404,075);

(iii) accelerated vesting of the next tranche of Mr. Draper’s then-outstanding RSUs (valued at $1,604,687 based on the closing p rice of

the Company’s common stock as of April 1, 2022); (iv) continued vesting of Mr. Draper’s then-outstanding PRSUs, with the number of

PRSUs earned based on the lesser of (A) actual performance during the full performance period or (B) actual performance during the

portion of the performance period ending on the termination date (valued at $1,540,222 based on the closing price of the Company’s

common stock as of April 1, 2022), and pro-rated based on the length of his employment with us during the applicable performance

period; (v) up to 12 months of COBRA continuation (valued at approximately $20,886); and (vi) Company-paid outplacement services

(valued at $4,200).

PAY RATIO

As required by Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K, we are providing the following information

regarding the relationship of the annual total compensation of our employees and the annual total compensation of Mr. Sievert, our

Chief Executive Officer. We have calculated the median of our employees’ 2022 total annual compensation (excluding our Chief

Executive Officer) to be $71,333. Our Chief Executive Officer’s total annual compensation for 2022, as set forth in the 2022 Summary

Compensation Table above (adjusted to include his employer-paid health benefits with respect to 2022), was $29,074,608. The

estimated ratio of the total compensation of Mr. Sievert to the median of the annual total compensation of our employees (other than

Mr. Sievert) was 408 to 1. We believe this pay ratio is a reasonable estimate calculated in a manner consistent with applicable rules of

the SEC. This information is being provided for compliance purposes. Neither the Compensation Committee nor management of the

Company used the pay ratio measure in making compensation decisions.

We identified the median employee by preparing a listing of 70,203 individuals (including only U.S. individuals and excluding

Mr. Sievert) who were employed by us on December 31, 2022, the last day of the calendar year, and examining the 2022 total

compensation paid to each such individual as reflected in our payroll records for 2022. We included all such employees (other than

Mr. Sievert), whether employed on a f ull-time, part-time, or seasonal basis who received a paycheck in the final pay period of the year.

As is permitted under Item 402(u) of Regulation S-K, we utilized the “de minimis” exemption to exclude all 114 of our non-U.S.

employees from the dataset, which non-U.S. employees represent approximately 0.16% of our total population (calculated using

70,203 U.S. employees and 114 non-U.S. employees). A list of the excluded employees and their respective countries is provided in

the following table:

Country # Employees Country # Employees Country # Employees Country # Employees

Argentina 1 Colombia 1 Japan 6 Sweden 3

Australia 5 Denmark 2 Mexico 5 Switzerland 1

Austria 3 France 5 Netherlands 6 Taiwan 1

Belgium 1 Germany 11 New Zealand 1 United Kingdom 19

Brazil 4 Hong Kong 6 Philippines 2

Canada 6 India 10 S. Korea 2

China 1 Italy 3 Singapore 9

We did not make any assumptions, adjustments, or estimates with respect to total compensation paid, and we did not annualize the

compensation for any employees that were not employed by us for all of 2022. We believe the use of total compensation paid for all

employees as reflected in our payroll records is a consistently applied compensation measure due to our large part-time, retail and

customer service employee population and practice of granting annual equity awards across our broad employee base.

Using the method described above, we identified a small sample of 15 employees, consisting of the median employee and 14 other

employees whose gross pay was very close to the median employee’s gross pay (“median group”). We then calculated annual total

compensation for such employees using the same methodology we use for our Named Executive Officers as set forth in the 2022

Summary Compensation Table in this proxy statement, taking into account employer-paid costs for 2022 health benefits, and selected

the median employee from this median group. We believe that our median employee’s compensation reasonably reflects the actual

annual compensation of our employees generally in terms of realized pay and benefits.

“Compensation Actually Paid” excludes the Stock Awards column from the relevant fiscal year’s Summary Compensation Table total. The equity values utilized in determining

“Compensation Actually Paid” instead reflect the aggregate of the following components, as applicable: (i) the fair value as of the end of the listed fiscal year of unvested equity awards

granted in that year; (ii) the change in fair value during the listed fiscal year of equity awards granted in prior years that remained outstanding and unvested at the end of the listed fiscal

year; and (iii) the change in fair value during the listed fiscal year through the vesting date of equity awards granted in prior years that vested during the listed fiscal year, less the fair value

at the end of the prior year of awards granted prior to the listed fiscal year that failed to meet applicable vesting conditions during the listed fiscal year. Equity values are calculated in

accordance with ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of the grant. For additional information

regarding the valuation assumptions used to calculate the fair value of our equity awards, please see the notes to our financial statements in our Annual Report on Form 10-K for the

applicable fiscal year.

TMUS Total Shareholder Return represents cumulative TSR on a fixed investment of $100 in our common stock for the period beginning on the last trading day of 2019 through the end of

reported above and over the three-year cumulative period shows how the compensation awarded fluctuated year-over-year, primarily based on our stock price as of the last day of the listed

fiscal year, among other factors.

The Company has identified Free Cash Flow as the company-selected measure for the pay versus performance disclosure, as it represents the most important financial performance measure

used to link compensation actually paid to the PEO and the Non-PEO NEOs in 2022 to the Company’s performance. See Appendix A to this Proxy Statement for a reconciliation of Free Cash

Flow, a non-GAAP measure, to the most directly comparable GAAP measure.

Relationship Between Compensation Actually Paid and Performance Measures

The table below reflects the relationship between the “Compensation Actually Paid” to Mr. Sievert, our PEO, and the average

compensation actually paid to the Non-PEO NEOs decreased by 40% and 42%, respectively, compared to a 155% increase in our

Free Cash Flow over the same time period.

Relationship Between the Company’s TSR and the Peer Group TSR. Peer Group TSR decreased by 19% from 2020 to 2022 as

compared to the Company’s TSR, which increased by 79% over the same time period. As the values change considerably from year-to-

year based on stock price performance, they further demonstrate the “pay-for-performance” compensation philosophy of our executive

compensation program. As the table demonstrates, the compensation of our PEO and the Non-PEO NEOs is higher when our stock

price performs well, and lower when the stock price does not perform as well, demonstrating the clear alignment of interests of our

PEO and the Non-PEO NEOs and our stockholders.

PAY VERSUS PERFORMANCE TABULAR LIST

We believe the following performance measures represent the most important financial performance measures used by us to link

compensation actually paid to our NEOs for the fiscal year ended December 31, 2022:

• US GAAP Service Revenue;

• Core Adjusted EBITDA; and

• Free Cash Flow.

In the “Compensation Discussion and Analysis” section of this Proxy Statement, we provide greater detail on the elements of our

executive compensation program and our “pay-for-performance” compensation philosophy. We believe the Company’s executive

compensation program appropriately rewards our PEO and the Non-PEO NEOs for Company and individual performance, promotes

retention of our senior leadership team and supports long-term value creation for our stockholders.

PROPOSAL 4:

ADVISORY VOTE ON THE FREQUENCY

OF FUTURE ADVISORY VOTES

TO APPROVE THE COMPENSATION PROVIDED TO THE COMPANY’S NAMED EXECUTIVE OFFICERS

Pursuant to Section 14A of the Exchange Act, we are asking stockholders to vote on an advisory basis on whether future advisory

votes to approve the compensation of our named executive officers (i.e., the say-on-pay vote reflected in Proposal Number 3 above)

should occur every year, every two years or every three years. The Board previously determined to hold triennial say-on-pay votes

starting with the 2017 annual meeting of stockholders.

We urge stockholders to review the information presented in connection with Proposal No. 3 in this proxy statement, as well as the

“Compensation Discussion and Analysis” section, compensation tables and related narrative discussion in this proxy statement for a

more detailed discussion of our compensation programs and policies and the compensation paid to our Named Executive Officers.

The Board has determined that holding an advisory “say-on-pay” vote every three years is most appropriate for the Company and

recommends that stockholders vote to hold such advisory votes in the future every three years. The Board believes that holding an

advisory say-on-pay vote every three years offers the closest alignment with the Company’s approach to executive compensation and

its underlying philosophy that seek to enhance the long-term growth of the company and to attract, retain and motivate our executive

officers over the long term. The Board believes a three-year cycle for the advisory say-on-pay vote will provide investors the most

meaningful timing alternative by which to evaluate the effectiveness of our executive compensation strategies and their alignment with

the company’s business and results of operations. We carefully review changes to our program to maintain the consistency and

credibility of the program, which is important in motivating and retaining our employees. The Board therefore also believes that a

three-year vote cycle for the advisory say-on-pay vote will give the Board sufficient time to thoughtfully consider the results of the

advisory vote and to implement any desired changes to our executive compensation policies and procedures.

Although this vote on the frequency of future advisory say-on-pay votes is advisory and non-binding, the Board and the Compensation

Committee value stockholders’ opinions and will consider the outcome of the vote when considering the frequency of future advisory

say-on-pay votes.

PROPOSAL 5:

APPROVAL OF T-MOBILE US, INC.

2023 INCENTIVE AWARD PLAN

Background

Our Board adopted the T-Mobile US, Inc. 2023 Incentive Award Plan (the “Plan”) on March 24, 2023, subject to stockholder approval.

Awards under the Plan provide employees, consultants and directors an opportunity to acquire or increase an ownership stake in our

Company, which we believe will enhance our ability to attract, retain and motivate highly qualified service providers who make or are

expected to make important contributions to the Company and align their economic interests with those of our stockholders. A copy of

the Plan is included as Annex A to this Proxy Statement, and the description of the material terms of the Plan in this Proposal is

qualified in its entirety by the full text of the Plan.

The Plan is intended to replace the 2013 Plan and the 2015 Plan (together, the “Prior Plans”). If our stockholders approve the Plan, the

Plan will become e ffective on June 16, 2023 (the “Effective Date”) and will supersede and replace the Prior Plans, and no further

awards will be granted under the Prior Plans from and after the Effective Date. However, the terms and conditions of the Prior Plans

will continue to govern any outstanding awards granted thereunder. If the Plan is not approved by our stockholders, then the Plan will

not become effective, the Prior Plans will continue in full force and effect, and we may continue to grant awards under the Prior Plans,

subject to their respective terms, conditions and limitations, using the shares available for issuance thereunder.

Stockholder Approval

Stockholder approval of the Plan is necessary in order for us to meet the stockholders’ approval requirements of NASDAQ, and to

grant stock options that qualify as incentive stock options, as defined under Code Section 422.

Reasonable Equity Dilution and Key Historical Equity Metrics

In determining the number of shares of common stock to request for approval to reserve for issuance under the Plan, our management

team worked with the Compensation Committee to evaluate a number of factors, including our recent share usage under each of the

Prior Plans, anticipated share usage under the Plan, and criteria expected to be utilized by institutional proxy advisory firms in

evaluating our proposal for the Plan. Specifically, our Compensation Committee considered the following:

• In fiscal years 2020, 2021 and 2022, equity awards representing a total of approximately 7,991,353 shares, 5,894,167 shares

and 5,971,037 shares, respectively, were granted under the 2013 Plan and the 2015 Plan, for an annual equity burn rate of

0.70%, 0.47% and 0.48%. The Company’s three-year average burn rate is as follows:

Year

Number of

Subject to

Awards

Weighted

Average

Basic

Common

Burn Rate

(%)

2020 7,991,353 1,144,206,326 0.70

2021 5,894,167 1,247,154,988 0.47

2022 5,971,037 1,249,763,934 0.48

Average Three-Year Burn Rate: 0.55

• Equity burn rate is calculated by dividing (i) the number of shares subject to equity awards granted (including time-based

restricted stock units and performance-based restricted stock units, after taking into account adjustments to performance-

based awards on actual performance) during the fiscal year by (ii) the number of shares outstanding at the end of the fiscal

year. We expect the proposed aggregate share reserve under the Plan to provide us with enough shares for awards for

approximately 5 years, assuming we continue to grant awards consistent with our current practices and historical usage, as

reflected in our historical burn rate, and further dependent on the price of our shares and hiring activity in the coming years,

forfeitures of outstanding awards, and noting that future circumstances may require us to change our current equity grant

practices.

PROXY STATEMENT 2023

Proposal 5: Approval of T-Mobile US, Inc. 2023 Incentive Award Plan

• As of March 31, 2023, 9,297,695 shares (assuming maximum performance of all then-outstanding PRSUs) remained available

for issuance under the Prior Plans, which are our only incentive award plans with shares available for issuance. In fiscal years

2020, 2021 and 2022, the end of year overhang rate was approximately 3.37%, 2.98% and 2.40%, respectively. If the Plan is

approved, we expect our overhang at the end of fiscal year 2023 will be approximately 4.50%. Overhang is calculated by

dividing (i) the sum of the number of shares subject to equity awards outstanding at the end of the fiscal year plus shares

remaining available for issuance for future awards (inclusive of our 2014 ESPP) at the end of the fiscal year by (ii) the number

of shares outstanding at the end of the fiscal year.

Additionally, as of March 31, 2023, outstanding grants under all of our equity plans (including the Prior Plans), and shares remaining

available for grant under the Prior Plans, are provided in the table below:

Available for Issuance (under both Prior Plans) 9,297,695

Stock Options Outstanding 457,767

Unvested Restricted Stock Units Outstanding 9,313,604

Unvested Performance Restricted Stock Units Outstanding 2,359,367

Unvested Restricted Stock Awards Outstanding —

Common Stock Outstanding 1,204,696,325

Weighted Average Exercise Price of Stock Options Outstanding $56.4546

Weighted-Average Remaining Duration (Years) of Stock Options Outstanding 2.3437 years

Employee Stock Purchase Plan 3,921,804

In light of the factors described above, and the fact that the ability to continue to grant equity compensation is vital in our view to our

ability to continue to attract and retain employees in the extremely competitive labor markets in which we compete, our Board has

determined that the size of the share reserve under the Plan is reasonable and appropriate at this time.

Material Terms of the Plan

The material features of the Plan are described below. This summary is qualified by reference to the full text of the Plan, a copy of

which is attached as Annex A to this Proxy Statement.

Purpose. The Plan is intended to enhance our ability to attract, retain and motivate highly qualified persons who make (or are

expected to make) important contributions to our Company by providing these individuals with an opportunity to acquire or increase a

direct proprietary interest in the operations and future success of our Company via equity ownership and/or equity-linked

compensation. Our Board believes that equity ownership opportunities and/or equity-linked compensatory opportunities are necessary

to remain competitive in its industry and are essential to recruiting and retaining the highly qualified employees who help us meet our

goals.

Eligibility. Our employees, consultants and non-employee directors, and employees and consultants of our affiliates, will be eligible to

receive awards under the Plan; however incentive stock options may only be granted to our employees. As of March 31, 2023, there

were approximately 73,000 employees and consultants and six non-employee directors eligible to receive awards under the Plan.

Administration. The Plan will be administered by the Board with respect to awards to non-employee directors and by the

Compensation Committee with respect to other participants, each of which may delegate its duties and responsibilities to one or more

of our officers or committees of our directors and/or officers (all such bodies and delegates are referred to collectively as the “plan

administrator”), subject to certain limitations that may be imposed under Section 16 of the Exchange Act, stock exchange rules or

other applicable laws, as applicable. T he plan administrator has the authority to take all actions and make all determinations under the

Plan, to interpret the Plan and grant agreements thereunder, to adopt, amend and repeal administrative rules for the Plan as it deems

advisable, and to remedy defects, ambiguities, omissions, or inconsistencies in the Plan or any grant agreement as it deems necessary

or appropriate. The plan administrator also has the authority to select employees, consultants and non-employee directors to receive

awards under the Plan, to grant awards under the Plan and set the terms and conditions (including vesting conditions) of awards

under the Plan, subject to the conditions and limitations in the Plan.

Shares Available for Awards. The aggregate number of shares of our common stock that may be issued pursuant to awards granted

under the Plan shall be the sum of (a) 24,000,000 shares and (b) any shares which remain available for issuance under the Prior Plans

as of the Effective Date. The maximum aggregate number of shares that may be issued pursuant to the exercise of incentive stock

options granted under the Plan will be 24,000,000. Shares granted under the Plan may be treasury shares, authorized but unissued

shares, or shares purchased on the open market.

If an award (or portion thereof) expires, lapses or is terminated, exchanged for or settled in cash, surrendered, repurchased or

canceled without having been fully exercised/settled or forfeited, in any case, in a manner that results in the Company acquiring

PROXY STATEMENT 2023

䡵

Proposal 5: Approval of T-Mobile US, Inc. 2023 Incentive Award Plan

shares covered by the award (at a price no greater than the price paid by the participant for such shares) or that results in the

Company not issuing shares under the award, any unused shares subject to the award will again be available for new grants under the

Plan. The payment of dividends or dividend equivalents in cash in conjunction with any outstanding award will not count against the

overall share limit. Shares that are (i) subject to a stock appreciation right (“SAR”) that are not issued in connection with the stock

settlement of the SAR on its exercise, (ii) purchased on the open market with the cash proceeds from the exercise of options,

(iii) tendered or withheld to satisfy the exercise price of an option, or (iv) tendered or withheld to satisfy tax withholding obligations

associated with an award, in any case, may not be used again for new grants of awards.

Awards granted under the Plan in substitution for any options or other equity or equity-based awards granted by an entity before the

entity’s merger or consolidation with us or our acquisition of the entity’s property or equity securities will not reduce the shares

available for grant under the Plan, but will (if applicable) count against the maximum number of shares that may be issued upon the

exercise of incentive stock options.

Limitations on Awards. The maximum number of shares of our common stock subject to options or SARs that may granted to any one

participant under the Plan during any twelve (12)-month period will be 5,000,000 shares. The maximum number of shares of our

common stock subject to awards other than options or SARs that may be granted to any one participant under the Plan any twelve

(12)-month period will be 2,000,000 shares. The maximum amount that may be paid in cash to any one participant during any twelve

(12)-month period with respect to one or more awards payable in cash will be (i) $25,000,000 for annual cash incentive awards or (ii)

$25,000,000 for other awards. In addition, the sum of any cash or other compensation and the value of awards (determined as of the

date of grant under the Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor

thereto) that may be granted to any non-employee director as compensation for services as a non-employee director during any fiscal

year may not exceed $1,000,000.

Awards. The Plan provides for the grant of stock options, including incentive stock options and nonqualified stock options, SARs,

restricted stock, restricted stock units, dividend equivalents, and other stock or cash based awards. Certain awards under the Plan

may constitute or provide for a deferral of compensation, subject to Section 409A of the Code, which may impose additional

requirements on the terms and conditions of such awards. All awards under the Plan are or will be set forth in award agreements

which detail the terms and conditions of the awards, including any applicable vesting and payment terms and post-termination

exercise limitations. A brief description of each award type follows.

• Stock Options. The plan administrator may determine the number of shares to be covered by each stock option, the exercise

price and such other terms, conditions, and limitations, including vesting, exercise, term and forfeiture provisions, applicable

to each stock option as it deems necessary or advisable. Stock options provide for the purchase of shares of our common

stock in the future at an exercise price set on the grant date. Stock options granted under the Plan may be either nonqualified

stock options or incentive stock options. Incentive stock options, by contrast to nonqualified stock options, may provide tax

deferral beyond exercise and favorable capital gains tax treatment to their holders if certain holding period and other

requirements of the Internal Revenue Code are satisfied. The exercise price of a stock option is determined by the plan

administrator at the time of grant but shall not be less than 100% of the fair market value of the underlying share on the date

of grant (or 110% in the case of incentive stock options granted to an employee who owns more than 10% of the Company),

except with respect to certain substitute options granted in connection with a corporate transaction. The term of a stock option

may not be longer than ten years (or five years in the case of incentive stock options granted to an employee who owns more

than 10% of the Company). No dividends or dividend equivalents will be payable with respect to stock options.

• SARs. The plan administrator may determine the number of shares to be covered by each SAR, the exercise price and such

other terms, conditions, and limitations, including vesting, exercise, term and forfeiture provisions, applicable to each SAR as

it deems necessary or advisable. S ARs entitle their holder, upon exercise, to receive from us an amount equal to the

appreciation of the shares subject to the award between the grant date and the exercise date. The exercise price of a SAR may

not be less than 100% of the fair market value of the underlying share on the date of grant, except with respect to certain

substitute SARs granted in connection with a corporate transaction. The term of a SAR may not be longer than ten years. N o

dividends or dividend equivalents will be payable with respect to SARs.

• Restricted Stock. Restricted stock is an award of nontransferable shares of our common stock which shares remain forfeitable

unless and until specified conditions are met. The plan administrator may determine the terms and conditions of restricted

stock awards, including the number of shares awarded, the purchase price, if any, to be paid by the recipient, the applicable

vesting conditions, and any rights to acceleration thereof. Vesting conditions determined by the plan administrator may

include continued service, performance and/or other conditions. The Plan provides that dividends payable with respect to

restricted stock prior to the vesting of such restricted stock instead will be paid out to the participant only as and to the extent

that the applicable vesting conditions of the underlying award are subsequently satisfied and the restricted stock vests.

Dividends payable with respect to the portion of a restricted stock award that fails to vest will be forfeited.

• Restricted Stock Units. Restricted stock units are contractual promises to deliver shares of our common stock (or its equivalent

value in cash or other consideration) in the future, which may also remain forfeitable unless and until specified conditions are

䡵

PROXY STATEMENT 2023

Proposal 5: Approval of T-Mobile US, Inc. 2023 Incentive Award Plan

met (which may include attainment of performance criteria). Delivery of the shares underlying restricted stock units may be

deferred under the terms of the award or at the election of the participant if the plan administrator permits such a deferral. The

terms and conditions applicable to restricted stock units are determined by the plan administrator, subject to the conditions

and limitations contained in the Plan.

• Other Stock or Cash Based Awards. Other stock or cash based awards are awards of cash, fully vested shares of our common

stock and other awards valued, wholly or partially, by reference to, or otherwise based on, shares of our common stock or other

property. Other stock or cash based awards may be granted as standalone payments or awards or as payment in lieu of

compensation to which a participant is otherwise entitled. The plan administrator will determine the terms and conditions of

other stock or cash based awards, which may include any vesting terms and conditions as determined by the plan

administrator.

• Dividend Equivalents. Dividend equivalents represent the right to receive the equivalent value of dividends paid on shares of

our common stock and may be granted in tandem with restricted stock units or other stock or cash based awards. Dividend

equivalents will not be payable with respect to options or SARs. Dividend equivalents may be paid currently or credited to an

account for the participant, settled in cash or shares of our common stock and subject to the same restrictions on

transferability and forfeitability as the award to which it relates. Under the Plan, dividend equivalents payable with respect to

an award shall only paid to a participant to the extent that the vesting conditions of the underlying award are subsequently

satisfied and the award vests. Dividend equivalents payable with respect to the portion of the award that fails to vest will be

forfeited.

Adjustments; Certain Transactions. In the event of certain changes in our corporate structure, including any dividend, distribution,

combination, merger, recapitalization or other corporate transaction, the plan administrator may make appropriate adjustments to the

terms and conditions of outstanding awards under the Plan to prevent the dilution or enlargement of the benefits or intended benefits

under the Plan, to facilitate the transaction or event or to give effect to applicable changes in law or accounting standards. In addition,

in the event of certain non-reciprocal transactions with our stockholders known as “equity restructurings,” the plan administrator will

make equitable adjustments to the Plan and to outstanding awards granted thereunder as it deems appropriate to reflect the

transaction, which may include adjusting the number and type of securities subject to each outstanding award and/or the exercise

price or grant price of each outstanding award, granting new awards, and making a cash payment to participants.

Effect of Change in Control. In the event of a “change in control” of the Company, outstanding awards will (i) with respect to any

award held by a non-employee director, become fully vested and exercisable (as applicable) immediately prior to the change in

control, (ii) with respect to any award held by an employee or consultant, to the extent that the outstanding awards are not assumed,

substituted, converted or replaced by a successor entity, become fully vested and exercisable (as applicable) immediately prior to the

change in control and (iii) with respect to any award held by an employee or consultant that is assumed, substituted, converted or

replaced by a successor entity and such employee or consultant experiences a qualifying termination within one year of the change in

control of the Company, then such award will become fully vested and exercisable (as applicable). For purposes of the preceding

sentence, performance awards will be deemed satisfied and, as applicable, vest and be paid at the greater of (x) target or (y) the

actual level of performance determined as if the applicable performance period had ended as of the last trading day immediately

preceding the change in control (or such other date prior to the change in control as determined by the plan administrator to be

necessary or appropriate based on the applicable performance goal)

Foreign Participants and Transferability. The plan administrator may modify awards granted to participants who are foreign nationals

or employed outside the United States or establish subplans or procedures to address differences in laws, rules, regulations or

customs of such foreign jurisdictions. Awards under the Plan are generally non-transferable, except for certain beneficiary

designations, a domestic relations order (subject to the plan administrator’s consent), or by will or the laws of descent and

distribution, and are generally exercisable only by the participant. Any permitted transfer under the Plan will be without consideration

except as required by applicable law.

Tax Withholding. We have the authority to deduct and withhold from any payment otherwise due to a participant, or require a

participant to remit to us, an amount sufficient to satisfy any federal, state, local and foreign taxes required to be withheld under

applicable law with respect to any taxable event concerning a participant arising as a result of the Plan. With regard to tax

withholding obligations arising in connection with awards under the Plan, payment may be made through an agent’s electronic

platform or wire transfer of immediately available funds or, at the discretion of the plan administrator, by cash or check, by delivery of

shares of our common stock (including shares delivered by attestation and shares retained from the award creating the obligation), by

via broker-assisted sales, or by any combination of the foregoing.

Claw-back. All awards granted under the Plan (including any proceeds, gains or other economic benefits received by any participant

in connection with such awards) will be subject to any compensation recovery policy that may be implemented by the Company

(whether or not currently in effect), including any compensation recovery policy adopted to comply with applicable law (including the

requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act and rules and regulations thereunder).

PROXY STATEMENT 2023

䡵

Proposal 5: Approval of T-Mobile US, Inc. 2023 Incentive Award Plan

No Repricing. Except in connection with certain corporate transactions, the Plan provides that the plan administrator may not, without

the approval of the Company’s stockholders, reduce the per-share exercise price of any outstanding option or SAR or grant any new

award or make any cash payment in substitution for or upon the cancellation of any outstanding option or SAR when the exercise

price of such option or SAR exceeds the fair market value of the underlying shares.

Plan Amendment and Termination. The Board may amend, suspend or terminate the Plan at any time; however, no amendment, other

than an amendment that is permitted by the applicable grant agreement, that increases the number of shares available for issuance

under the Plan or that is made to comply with applicable law, may materially and adversely affect an outstanding award without the

consent of the affected participant. Stockholder approval will be obtained for any amendment to increase any individual or

non-employee director award limit, to amend, modify, terminate or suspend the stock option and SAR repricing provisions, and to the

extent necessary to comply with applicable laws. The Plan (if approved by our stockholders) will remain in effect until the tenth

anniversary of the Effective Date, unless earlier terminated by our Board. No incentive stock option may be granted under the Plan

after the tenth anniversary of the earlier of the date on which the Board adopted the Plan and the date on which our stockholders

approve the Plan.

Federal Income Tax Consequences of the Plan

The following is a general summary of the current law of the principal U.S. federal income tax consequences of awards under the Plan.

The following summary discusses the general federal income tax principles applicable to the Plan and is provided only for general

information. This summary is not intended to be exhaustive and, among other considerations, does not describe state, local, or foreign

tax consequences. Tax considerations may vary from locality to locality and depending on individual circumstances. This summary is

not intended as tax advice to participants, who should consult their own tax advisors.

Non-Qualified Stock Options. If a participant is granted a nonqualified stock option under the Plan, the participant should not have

taxable income on the grant of the option. Generally, the participant should recognize ordinary income at the time of exercise in an

amount equal to the fair market value of the shares acquired on the date of exercise, less the exercise price paid for the shares. The

participant’s basis in the common stock for purposes of determining gain or loss on a subsequent sale or disposition of such shares

generally will be the fair market value of our common stock on the date the participant exercises such option. Any subsequent gain or

loss should be taxable as a long-term or short-term capital gain or loss. We or our subsidiaries or affiliates generally should be entitled

to a federal income tax deduction at the time and for the same amount as the participant recognizes ordinary income, subject to Code

limitations.

Incentive Stock Options. A participant receiving incentive stock options should not recognize taxable income upon grant or at the

time of exercise. However, the excess of the fair market value of the shares of our common stock received over the option exercise

price is an item of tax preference income potentially subject to the alternative minimum tax. If stock acquired upon exercise of an

incentive stock option is held for a minimum of two years from the date of grant and one year from the date of exercise and otherwise

satisfies the incentive stock option requirements, the gain or loss (in an amount equal to the difference between the fair market value

on the date of disposition and the exercise price) upon disposition of the stock should be treated as a long-term capital gain or loss,

and we should not be entitled to any deduction. If the holding period requirements are not met, the incentive stock option should be

treated as one that does not meet the requirements of the Code for incentive stock options and the participant should recognize

ordinary income at the time of the disposition equal to the excess of the amount realized over the exercise price, but not more than

the excess of the fair market value of the shares on the date the incentive s tock option is exercised over the exercise price, with any

remaining gain or loss being treated as capital gain or capital loss. We and our subsidiaries or affiliates generally are not entitled to a

tax deduction upon either the exercise of an incentive stock option or upon disposition of the shares acquired pursuant to such

exercise, except to the extent that the participant recognizes ordinary income on disposition of the shares, subject to Code limitations.

Restricted Stock Units. A participant generally will not recognize taxable income upon grant of restricted stock units. When cash or

shares of common stock are delivered under the terms of the award, the participant should recognize ordinary income equal to the

cash payment or the fair market value of the shares delivered, as the case may be, less any amount (if any) paid by the participant for

such shares, and we or our subsidiaries or affiliates generally should be entitled to a corresponding deduction at that time, subject to

Code limitations.

Other Awards. The current federal income tax consequences of other awards authorized under the Plan generally follow certain basic

patterns: SARs are taxed and deductible in substantially the same manner as nonqualified stock options; nontransferable restricted

stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price

paid, if any, only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant through

a Code Section 83(b) election); dividend equivalents, cash awards and other stock awards are generally subject to tax at the time of

payment. We and our subsidiaries or affiliates generally should be entitled to a federal income tax deduction at the time and for the

same amount as the participant recognizes ordinary income.

Proposal 5: Approval of T-Mobile US, Inc. 2023 Incentive Award Plan

Application of Code Section 409A. Certain types of awards under the Plan may constitute, or provide for, a deferral of compensation

subject to Code Section 409A. Unless certain requirements set forth in Code Section 409A are complied with, holders of such awards

may be taxed earlier than would otherwise be the case (e.g., at the time of vesting instead of the time of payment) and may be subject

to an additional 20% penalty tax (and, potentially, certain interest penalties and additional state taxes). To the extent applicable, the

Plan and awards granted under the Plan are intended to be structured and interpreted in a manner intended to either comply with or

be exempt from the requirements of Code Section 409A and the Department of Treasury regulations and other interpretive guidance

that may be issued under Code Section 409A. To the extent determined necessary or appropriate by the plan administrator, the Plan

and applicable award agreements may be amended to further comply with Code Section 409A or to exempt the applicable awards

from Code Section 409A.

Stock Price

The closing price of the Company’s common stock on NASDAQ as of March 31, 2023 was $144.84 per share.

New Plan Benefits

Awards that our named executive officers, directors, other executive officers and other employees may receive under the Plan will be

determined in the discretion of our Board or Compensation Committee, as applicable, in the future, and neither our Board nor our

Compensation Committee has made any determination with respect to future grants to any persons under the Plan as of the date of

this Proxy Statement. Therefore, it is not possible to determine the f uture benefits that will be received by participants under the Plan,

or the benefits that would have been received by such participants if the Plan had been in effect in the fiscal year ended

December 31, 2022.

1 The Metro Communications, Inc. 2010 Equity Incentive Plan, the Layer3 TV, Inc. 2013 Stock Plan, the Sprint Corporation 2007 Omnibus Incentive Plan and the Sprint Corporation Amended

and Restated 2015 Plan were assumed by the Company in connection with prior mergers or other acquisitions and have not been approved by T-Mobile’s stockholders. With the exception

of the Sprint Corporation Amended and Restated 2015 Plan, no further awards may be granted under any of these plans.

2 Represents the number of underlying shares of common stock associated with outstanding options or RSUs and PRSUs, as applicable, granted under our 2013 Plan (with PRSUs calculated

assuming target performance).

3 Represents the number of shares available for future issuance under stockholder approved equity compensation plans as of December 31, 2022, which is comprised of 6,837,835 shares

under our 2013 Plan and 4,985,230 shares subject to outstanding rights under the 2014 ESPP (of which 1,063,426 were purchased on March 31, 2023 for the offering period that included

December 31, 2022).

4 Represents the number of underlying shares of common stock associated with outstanding options, RSUs and PRSUs, as applicable, granted under the Sprint Corporation Amended and

Restated 2015 Plan (with PRSUs calculated assuming target performance). In addition, 310,859 shares of common stock may be issued upon the exercise of outstanding options, RSUs and

PRSUs (calculated assuming target performance) under our other non-stockholder approved equity compensation plans as follows: (i) Metro Communications, Inc. 2010 Equity Incentive

Plan, 10,166 shares; (ii) Layer3 TV, Inc. 2013 Stock Plan, 7,127 shares; and (iii) Sprint Corporation 2007 Omnibus Incentive Plan, 293,566 shares.

Plan) is $55.02.

6 Represents the number of shares available for future issuance under the Sprint Corporation Amended and Restated 2015 Plan as of December 31, 2022.

7 Represents the total number of shares available for future issuance under our equity compensation plans as of December 31, 2022, which is comprised of 6,837,835 shares under our 2013

Plan, 8,243,526 shares under the Sprint Corporation Amended and Restated 2015 Plan, and 4,985,230 shares subject to outstanding rights under the 2014 ESPP (of which 1,063,426 were

purchased on March 31, 2023 for the offering period that included December 31, 2022). The 2014 ESPP allows eligible employees to purchase shares at 85% of the lower of the fair market

value on the first or last trading day of the six-month offering period. Pursuant to the terms of the 2014 ESPP, the number of shares available for issuance under the 2014 ESPP will

automatically increase each year on the first day of our fiscal year in an amount equal to the lesser of (i) 5,000,000 shares and (ii) such smaller number as determined by the Compensation

Committee, if any. Since the adoption of the 2014 ESPP in 2014, the Compensation Committee has determined that no additional shares were necessary to be added to the 2014 ESPP

(and, accordingly, these automatic increases have not occurred in past years); however, on each of January 1, 2020 and January 1, 2021, the shares reserved for issuance pursuant to the

2014 ESPP were automatically increased by 5,000,000.

SPRINT CORPORATION AMENDED AND RESTATED 2015 OMNIBUS INCENTIVE PLAN

In connection with the closing of the Sprint Combination, T-Mobile assumed the 2015 Plan and may grant awards covering T-Mobile

common stock under the 2015 Plan. The material terms of the 2015 Plan are described below:

Administration. The 2015 Plan is administered by the Compensation Committee, which has the authority to interpret, construe and

make determinations regarding any provision of the 2015 Plan and any award granted thereunder. In addition, certain administrative

duties may be delegated to the Company’s officers, directors or advisors, subject to limitations contained in the 2015 Plan.

Share Reserve. As of December 31, 2022, the maximum number of shares of our common stock which may be granted under the 2015

Plan was 8,243,526. If any award granted under the 2015 Plan expires, is forfeited or otherwise terminates without being fully

exercised, or is settled in cash, such shares will again be available for grant under the 2015 Plan. Shares of common stock tendered or

withheld for the payment of the exercise price of an award, or to satisfy any applicable withholding taxes upon exercise, vesting or

payment of an award, will not again be available for issuance under the 2015 Plan.

䡵

PROXY STATEMENT 2023

Proposal 5: Approval of T-Mobile US, Inc. 2023 Incentive Award Plan

Eligibility. Employees, directors, consultants and other service providers who were engaged by Sprint and its subsidiaries prior to the

closing of the Sprint Combination or were hired by us following the closing of the Sprint Combination are eligible to receive awards

under the 2015 Plan.

Awards. We may grant awards of stock options (including incentive stock options (as defined in Code Section 422) (“ISOs”)

and non-qualified stock options), appreciation rights, RSUs, restricted stock, performance shares, performance units, and other stock-

based or cash-based awards under the 2015 Plan. Subject to adjustment as described in the 2015 Plan, no individual may be granted

stock options (or other awards with rights which are substantially similar to stock options) for more than 5,000,000 shares of common

stock in any fiscal year.

• Stock Options and Appreciation Rights. Stock options are rights to purchase shares of common stock upon the exercise

thereof at a fixed exercise price that is set on the grant date. Appreciation rights generally entitle their holder, upon exercise, to

receive an amount in cash or shares equal to the appreciation of the shares subject to the award between the grant date and

exercise date. Stock options granted under the 2015 Plan may be ISOs or non-qualified stock options. In no event may a stock

option have a term extending beyond the tenth anniversary of the date of grant (or the fifth anniversary of the date of grant for

ISOs granted to certain significant stockholders). The exercise price of any stock option or appreciation right granted under

the 2015 Plan may not be less than 100% of the fair market value of the shares of common stock underlying the option on the

applicable date of grant (or 110% in the case of ISOs granted to certain significant stockholders).

• RSUs. An RSU represents the right to receive one share of common stock (or its fair market value in cash) at a future date

upon the satisfaction of specific conditions set forth in the applicable award agreement.

• Other Awards. Restricted stock is an award of nontransferable shares of our common stock that are subject to certain vesting

conditions and other restrictions. Performance shares and performance units are awards that become payable, in cash or

shares, upon the satisfaction of specified performance objectives set forth in the applicable award agreement. Other stock or

cash-based awards are awards of cash, fully vested shares of our common stock and other awards valued wholly or partially by

referring to, or otherwise based on, shares of our common stock.

Terms and Conditions of Awards. Each award is evidenced by an award agreement specifying the applicable terms and conditions

(including vesting conditions and any terms and conditions related to forfeiture and termination of service) of such award, which are

determined by the Compensation Committee at the time of grant. Except as set forth in an award agreement, unvested awards are

forfeited without payment upon a participant’s termination of service.

Adjustments; Change in Control. In the event of certain changes in our capital structure, including any stock dividend, stock split,

combination of shares, recapitalization or other change in the Company’s capital structure, or any merger, consolidation, spin-off,

split-off, spin-out, reorganization, or other corporate transaction or event having a similar effect, the Board may adjust outstanding

awards under the 2015 Plan and the share limit under the 2015 Plan to prevent dilution or enlargement of the rights under the 2015

Plan. Unless otherwise provided by the Compensation Committee, if there is a “change in control” of the Company (as defined in the

2015 Plan) and the resulting entity does not assume, convert or replace awards outstanding under the 2015 Plan, such awards will

become fully vested and all restrictions thereon will lapse, with any performance objectives deemed satisfied at target level. If the

resulting entity assumes, converts or replaces such outstanding awards, any applicable performance objectives will be deemed

attained at target level and all outstanding awards will become fully vested upon the participant’s involuntary termination of service

without cause or resignation with good reason, in either case, within 18 months following the change in control (or within six months

prior to the change in control in certain circumstances). Notwithstanding the foregoing, in the event of a change in control, the Board

may cancel and cash-out outstanding options upon a change in control.

280G Cutback. The 2015 Plan contains a Code Section 280G “cutback” provision pursuant to which any “parachute payments”

(including accelerated vesting of awards under the 2015 Plan) that become payable to a participant will be reduced so that such

payments are not subject to the excise tax under code Section 4999 (except as otherwise provided in an agreement between the

participant and the Company).

Transferability; Clawback; Recoupment. Generally, awards granted under the 2015 Plan are not transferable except by will or the laws

of descent and distribution, or as otherwise permitted by the Board or the Compensation Committee. All awards granted under the

2015 Plan are subject to deduction, forfeiture, recoupment or similar requirement in accordance with any clawback policy that may be

implemented by the Company from time to time or any other agreement or arrangement with a grantee. In addition, to the extent set

forth in an award agreement, a participant may be required to forfeit, return or repay to the Company (as applicable) his or her awards

or shares acquired pursuant to awards (or the fair market value thereof, if such shares are disposed of) if the Board or the

Compensation Committee determines that the participant has engaged in any detrimental activity (as defined in the 2015 Plan) during

his or her service with the Company or a subsidiary thereof or within a specified period thereafter.

Amendment and Termination. The 2015 Plan will automatically terminate on the tenth anniversary of the date the 2015 Plan became

effective, unless earlier terminated. Our Board may amend, suspend or terminate the 2015 Plan at any time; however, except in

connection with certain changes in capital structure, stockholder approval is required for any amendment that would (i) materially

䡵

increase the benefits accruing to participants under the 2015 Plan, (ii) materially increase the number of shares of common s tock

which may be issued thereunder, (iii) materially modify the requirements for participation in the 2015 Plan, or (iv) amend any

outstanding options to reduce the exercise price thereof, cancel any options in exchange for cash or another award with a lower

exercise price, or otherwise “reprice” options, and any amendment that otherwise requires stockholder approval under applicable law

or the rules of the applicable stock exchange. In addition, except in connection with certain changes in capital structure, no

amendment may materially impair the rights of any participant without his or her consent.

PROXY STATEMENT 2023

PROPOSAL 6: APPROVAL OF T-MOBILE US, INC.

AMENDED AND RESTATED 2014

EMPLOYEE STOCK PURCHASE PLAN

Background

We originally adopted the 2014 ESPP, effective October 30, 2014, for the purpose of providing employees of our Company and our

designated subsidiaries or parent companies with an opportunity to acquire an equity ownership interest in the Company to

encourage such employees to remain in the employ of the Company and our designated subsidiaries or parent companies.

We are now requesting that our stockholders vote in favor of approving the T-Mobile US, Inc. Amended and Restated 2014 Employee

Stock Purchase Plan (the “2023 ESPP”), which amends and restates the 2014 ESPP in its entirety. Our Board approved the 2023 ESPP

on March 23, 2023, subject to stockholder approval. If our stockholders approve the 2023 ESPP, the 2023 ESPP will become effective

on June 16, 2023. If the 2023 ESPP is not approved by our stockholders, then the 2023 ESPP will not become effective, and the 2014

ESPP will continue in full force and effect until October 30, 2024 with the current share limit set forth in the 2014 ESPP.

A copy of the 2023 ESPP is included as Annex B to this Proxy Statement, and the description of the material terms of the 2023 ESPP

in this Proposal is qualified in its entirety by full the text of the 2023 ESPP. The following is an overview of the key changes to the

2014 ESPP contained in the 2023 ESPP.

• Increase in the 2023 ESPP’s share limit by approximately 10,100,000 shares, to a total of 14,000,000 shares of common stock

available for issuance under the 2023 ESPP;

• Remove the “evergreen” provision providing for annual increases to the 2014 ESPP’s share limit;

• Decrease the number of shares that may be purchased by an employee during an offering period from 4,000 shares to 2,000 shares;

• Clarify the procedures for suspending of an employee’s payroll deductions or contributions during an offering period;

• Extend the term of the 2023 ESPP by 10 years until the 10

anniversary of the date on which the 2023 ESPP is approved by

our stockholders; and

• Provide the plan administrator with more flexibility in the administration of the 2023 ESPP with respect to determining the

length of, and other terms and conditions applicable to, offering and purchase periods under the 2023 ESPP (within the limits

of the 2023 ESPP).

We believe that maintaining an employee stock purchase plan enhances employees’ sense of participation in our performance, aligns

their interest with those of our stockholders, and provides a significant retention incentive that ultimately benefits our stockholders.

Stockholder Approval

Stockholder approval of the 2023 ESPP is necessary in order for us to meet the stockholders’ approval requirements of NASDAQ and

to meet the requirements of Code Section 423.

Key Historical Equity Metrics

In determining the number of shares of common stock to request for approval to reserve for issuance under the 2023 ESPP, our

management team worked with the Compensation Committee to evaluate a number of factors, including our recent share usage under

the 2014 ESPP, anticipated share usage under the 2023 ESPP, and criteria expected to be utilized by institutional proxy advisory firms

in evaluating our proposal for the 2023 ESPP. Specifically, our Compensation Committee considered the following:

• As of March 31, 2023, the 2014 ESPP had 3,921,804 shares available for future issuance. If the 2023 ESPP is not approved, the

2014 ESPP will terminate effective October 30, 2024 (and, if the 2014 ESPP were not set to expire October 30, 2024, we

estimate that we would have enough shares remaining under the 2014 ESPP to continue making awards for approximately one

year, assuming we continue to grant awards consistent with our historical usage and expected practices, and noting that

future circumstances may require us to make changes to our expected practices).

• By increasing the share reserve under the 2023 ESPP, we expect to be able to continue to provide our employees with the

opportunity to purchase shares of our common stock under the 2023 ESPP for approximately five years, assuming employee

participation in the 2023 ESPP is consistent with historical levels, and noting that future circumstances may require us to

change our expected practices.

Proposal 6: Approval of T-Mobile US, Inc. Amended and Restated 2014 Employee Stock Purchase Plan

In light of the factors described above, and the fact that the ability to continue to offer an employee stock purchase plan is vital in our

view to our ability to continue to attract and retain employees in the extremely competitive labor markets in which we compete, our

Board has determined that the size of the share reserve under the Plan is reasonable and appropriate at this time.

Material Terms of the 2023 ESPP

The material features of the 2023 ESPP are described below. This summary is qualified by reference to the full text of the 2023 ESPP,

a copy of which is attached as Annex B to this Proxy Statement.

Purpose. The 2023 ESPP’s purpose is to provide employees with an opportunity to acquire an equity ownership interest in the

Company and to encourage employees to remain in the employ of the Company.

Eligibility. Generally, all employees of the Company and its designated subsidiaries are eligible to participate in the 2023 ESPP,

although the Compensation Committee may impose additional eligibility requirements consistent with the Code. However, any

employee who owns or is deemed to own through attribution 5% or more of the total combined voting power or value of all classes of

stock of the Company or any subsidiary is excluded from participating in the 2023 ESPP. As of March 31, 2023, there were

approximately 73,000 employees eligible to participate in the 2023 ESPP.

Administration. The 2023 ESPP will be administered by the Compensation Committee, unless otherwise determined by the Board.

The Board may at any time vest in itself any authority or duties for administration of the 2023 ESPP. The Compensation Committee has

the full and exclusive discretionary authority to construe and interpret the 2023 ESPP and the rights granted under it, to establish rules

and regulations for the administration of the 2023 ESPP, to establish offering and purchase periods under the 2023 ESPP, to

determine the terms, conditions and provisions of each offering under the 2023 ESPP, to designate f rom time to time which of our

subsidiaries will participate in the 2023 ESPP, and to amend, suspend or terminate the 2023 ESPP (subject to the limitations of the

2023 ESPP).

Shares Available for Awards. Subject to adjustment by the plan administrator in the event of certain changes in our corporate

structure (as described below), the aggregate number of shares of common stock reserved for sale and authorized for issuance under

the 2023 ESPP will be 14,000,000 shares. If an option granted under the 2023 ESPP terminates for any reason without the underlying

shares having been purchased, the shares of common stock not purchased under the option will again become available for issuance

under the 2023 ESPP. Shares granted under the 2023 ESPP may be treasury shares, authorized but unissued shares, or shares

purchased on the open market.

Participation. Employees may become participants in the 2023 ESPP for an offering period by completing an enrollment election form

prior to the enrollment date of the applicable offering period, which will designate a whole percentage of the employee’s

compensation to be withheld by us as payroll deductions under the ESPP during the offering period. Unless otherwise determined by

the plan administrator or changed by the participant, a participant’s enrollment election and designated payroll deduction or

contribution rate will continue for future offering periods (for so long as such participant remains eligible to participate in the 2023

Plan).

Offerings; Purchase Periods.

• Offerings; Purchase Periods. Under the 2023 ESPP, participants are offered the right to purchase shares of our common stock

at a discount during a series of offering periods. Unless otherwise determined by the plan administrator, offering periods under

the 2023 ESPP will be six (6) months, commencing on April 1 and October 1 of each year; provided, that an offering period

may be no more than five years long (or, if the purchase price may be less than 85% of the fair market value of our common

stock on the purchase date, no more than twenty-seven (27) months long). Accumulated employee payroll deductions will be

used to purchase shares of our common stock on each purchase date during an offering period. Unless otherwise determined

by the plan administrator, each offering period will have a single co-terminus six-month purchase period. The plan

administrator may, in its discretion, modify the terms of f uture offerings.

• Enrollment and Contributions. The 2023 ESPP permits participants to purchase our common stock through payroll deductions

of a whole percentage of their eligible compensation, which may not be less than 1% and may be up to a maximum

percentage determined by the plan administrator (which, in the absence of a contrary designation, will be 15% of eligible

compensation).

• Limitations on Purchases. Except as otherwise determined by the plan administrator, the maximum number of shares that may

be purchased by a participant during any offering period will be 2,000 shares. In addition, a participant may not subscribe for

more than $25,000 worth of shares under the 2023 ESPP per calendar year in which such rights to purchase stock are

outstanding (considered together with any other ESPP maintained by us or certain parent or subsidiary entities) based on the

fair market value of the shares at the time the option is granted.

䡵

PROXY STATEMENT 2023

Proposal 6: Approval of T-Mobile US, Inc. Amended and Restated 2014 Employee Stock Purchase Plan

• Options. On the first trading day of each offering period, each participant will be granted an option to purchase shares of our

common stock. Unless a participant has previously withdrawn his or her participation in, or has otherwise become ineligible to

participate in, the ESPP prior to any applicable purchase date, the option will be exercised on the applicable purchase date(s) during

the offering period to the extent of the payroll deductions accumulated during the offering period. The participant will purchase the

maximum number of whole shares of our common stock that his or her accumulated payroll deductions will buy at the purchase

price, subject to the participation limitations described above, and any remaining amount in the participant’s account will be returned

to the participant, except that any amounts that are not sufficient to purchase a whole share of our common stock will be retained in

the Participant’s Account for the subsequent Purchase Period or Offering Period. However, the plan administrator has the discretion

to provide that fractional shares will be purchased on the applicable purchase date(s).

• Purchase Price. The purchase price for each offering period will be 85% of the lesser of (i) the closing trading price of a share

of our common stock on the first day of the offering period or (ii) the closing trading price of a share of our common stock on

the purchase date of the offering period, unless the plan administrator determines to increase the purchase price (provided

that such purchase price may be no more than 100% of the closing trading price of a share of our common stock on the first

day of the offering period or purchase date (as applicable)).

• Payroll Deduction Changes; Suspensions; Withdrawals; Terminations of Employment. Unless otherwise determined by the plan

administrator, a participant suspend his or her payroll deductions or contributions during an offering period by delivering a

notice of suspension to us within a time period determined by the plan administrator. Upon any such suspension, the

participant’s cumulative unapplied payroll deductions or contributions will remain in his or her account and will be applied to

the purchase of shares of common stock on the next occurring purchase date and such participant shall, at the end of such

offering period be treated as having withdrawn from the 2023 ESPP at the end of such offering period (unless the participant

re-enrolls in the 2023 ESPP for any subsequent offering period). In addition, a participant may withdraw his or her participation

in the 2023 ESPP by submitting written notice to us within a time period determined by the plan administrator, and upon such

withdrawal, either (as determined in accordance with procedures by the Committee) the participant’s cumulative unapplied

payroll deductions or contributions will remain in his or her account and will be applied to the purchase of shares of common

stock on the next occurring purchase date or such funds will be refunded to the participant. Participation in the ESPP ends

automatically upon a participant’s termination of employment.

Transfer Restrictions. A participant may not transfer (other than by will or the laws of descent and distribution or by certain

beneficiary designations) any option granted under the 2023 ESPP and, during a participant’s lifetime, options granted under the

2023 ESPP shall be exercisable only by such participant.

Adjustments; Certain Transactions. In the event of any increase or decrease in the number of shares of common stock resulting from

a stock split, reverse stock split, stock dividend, extraordinary cash dividend, combination or reclassification of the common stock or

recapitalization, reorganization, consolidation, split-up, spin-off or any other increase or decrease in the number of shares of common

stock effected without receipt of consideration by us, the plan administrator will, in order to prevent dilution or enlargement of the

benefits or potential benefits intended by us to be made available under the 2023 ESPP or with respect to any outstanding options

under the 2023 ESPP, proportionately adjust the number of shares authorized for issuance under the 2023 ESPP, the outstanding

options granted under the 2023 ESPP, the maximum number of shares that may be purchased by any one participant during an

offering period or purchase period, and the purchase price per share and the number of shares covered by each outstanding options.

In the event of any dissolution, liquidation, merger, consolidation or similar corporate transaction, any unusual or non-recurring events

affecting us, our affiliates or any of our financial statements, or any change in applicable law or accounting principles, the plan

administrator may make such adjustments it deems appropriate to prevent dilution or enlargement of rights in the number and class of

shares that may be purchased under the 2023 ESPP and in the number, class or price of s hares subject to options, in the number of

shares a participant is entitled to purchase and such other adjustments as it deems appropriate. In the event of any such transaction

or event, the plan administrator may elect to have the options under the 2023 ESPP assumed or substituted by a successor entity, to

set an earlier purchase date, to terminate all outstanding options either prior to their expiration or upon completion of the purchase of

shares of common stock on the next purchase date, or to take such other action deemed appropriate by the plan administrator.

Tax Withholding. We have the authority to deduct and withhold from any payment otherwise due to a participant, or require a

participant to remit to us, an amount sufficient to satisfy any federal, state, local and foreign taxes required to be withheld under

applicable law with respect to any taxable event concerning a participant arising as a result of the 2023 ESPP.

Amendment or Termination. The Board may amend, suspend or terminate the 2023 ESPP at any time, subject to stockholder approval

to the extent required under Code Section 423 or by any applicable securities exchange on which the common stock is then-traded,

except that the 2023 ESPP may not be amended in a manner that causes options issued under the 2023 ESPP to fail to meet the

requirements of Code Section 423. Unless earlier terminated by the Board, the 2023 ESPP shall automatically terminate on the tenth

anniversary of the date on which our stockholder approve the 2023 ESPP.

The plan administrator may, without stockholder approval, change or terminate the offering periods, limit the frequency and/or number

of changes in a participant’s payroll deduction or contribution rate, establish the exchange ratio applicable to amounts withheld in a

currency other than U.S. dollars, alter the purchase price for or length of an offering period in order to reduce or eliminate adverse

financial accounting consequences, and establish such other limitations or procedures as the plan administrator determines to be

advisable and as are consistent with the 2023 ESPP.

Federal Income Tax Consequences of the 2023 ESPP

The following is a general summary of the current law of the principal U.S. federal income tax consequences to us and our e mployees

under the 2023 ESPP. The following summary discusses the general federal income tax principles applicable to the 2023 ESPP and is

provided only for general information. This summary is not intended to be exhaustive and, among other considerations, does not

describe state, local, or foreign tax consequences. Tax considerations may vary from locality to locality and depending on individual

circumstances. This summary is not intended as tax advice to employees, who should consult their own tax advisors.

The 2023 ESPP is intended to qualify as an “employee stock purchase plan” under Code Section 423. For federal income tax

purposes, a participant in the 2023 ESPP generally will not recognize taxable income on the grant or exercise of an option under the

2023 ESPP, nor will we be entitled to any deduction at that time. Additionally, if applicable holding period requirements are met, the

participant should not recognize taxable income at the time of exercise. If stock acquired upon exercise of an option acquired under

the 2023 ESPP is held for a minimum of two years from the date of grant and one (1) year from the date of exercise, the participant (or

the participant’s estate) will recognize ordinary income measured as the lesser of (i) the excess of the fair market value of the shares at

the time of such sale or disposition (or death) over the purchase price or (ii) the excess of the fair market value of the shares on the

date the option was granted over the purchase price. Any additional gain will be treated as long-term capital gain.

If the holding period requirements are not met, the participant will recognize ordinary income at the time of the disposition equal to

the excess of the fair market value of the shares on the date the option is exercised over the purchase price, with any remaining gain

or loss being treated as capital gain or capital loss. However, if the holding period requirements are not met and the amount realized

at the time of disposition is less than the fair market value of the shares at the time of exercise, the participant will recognize ordinary

income to the extent of the excess of the fair market value of such shares on the date the option was exercised over the purchase

price for such shares, and a capital loss to the extent the fair market value of such shares on the exercise date exceeds the amount

realized upon disposition.

We or our subsidiaries or affiliates generally are not entitled to a federal income tax deduction upon either the exercise of an option or

upon disposition of the shares acquired pursuant to such exercise, except to the extent that the participant recognizes ordinary

income on disposition of the shares, subject to Code limitations.

Stock Price

The closing price of the Company’s common stock on NASDAQ as of March 31, 2023 was $144.84 per share.

New Plan Benefits

The number of shares that may be purchased under the ESPP will depend on each employee’s voluntary election to participate, the

rate of contributions by such employees and the purchase price of the shares issuable under the 2023 ESPP at future dates.

Accordingly, it is not possible to determine the value of the future benefits which may be received by participants under the 2023

ESPP.

TRANSACTIONS WITH RELATED

PERSONS AND APPROVAL

Related Person Transactions

We are a participant in a number of related person transactions (as defined in the Related Person Transaction Policy described below)

with our significant stockholder, Deutsche Telekom and its affiliates. These transactions include important financing arrangements

and commercial arrangements pursuant to which we obtain or provide various services and/or license intellectual property or

technology. SoftBank and its affiliates ceased to be related persons (Related Person Transaction Policy described below) in 2022.

As noted below, certain transactions with Deutsche Telekom that occurred before the Metro Combination were not required to be

approved in accordance with our Related Person Transaction Policy as Deutsche Telekom did not qualify as a related person at the

time such transactions were entered into. Otherwise, each of the related person transactions with Deutsche Telekom or its affiliates

was reviewed and approved by the Audit Committee in accordance with our then-current Related Person Transaction Policy. The Audit

Committee considered, among other things, whether the terms of each transaction were comparable to those generally available in

arm’s-length transactions with unaffiliated third parties and whether the related person transaction is consistent with the best interests

of the Company. All factors that are considered by the Audit Committee are described below.

Related Person Transaction Policy

Under the Company’s written Related Person Transaction Policy, any proposed or existing transaction, arrangement or relationship

involving a director, director nominee, executive officer, or a member of the immediate family of any of the foregoing, or a greater than

5% owner of our stock (a “related person”), must be reviewed by our General Counsel to determine whether such transaction is a

related person transaction. A “related person transaction” is any transaction, arrangement or relationship or any series of transactions,

arrangements or relationships in which:

• the Company, or any of its subsidiaries, is, was or will be a participant;

• the aggregate amount involved exceeds, or may be expected to exceed, $120,000; and

• any related person has, had or will have a direct or indirect material interest.

A transaction, arrangement or relationship that is determined to be a related person transaction must be submitted to our Audit

Committee for review, approval or ratification based on certain factors, including the following:

• the nature of the related person transaction and the terms of the related person transaction;

• the extent of the related person’s interest in the transaction;

• the business reasons for the Company to enter into the related person transaction;

• whether the transaction involves the provision of goods or services to the Company that are available from unaffiliated third

parties;

• whether the terms are comparable to those generally available in arm’s-length transactions with unaffiliated third parties;

• whether the related person transaction is consistent with the best interests of the Company; and

• in the case of any related person transaction involving an outside director of the Company, the potential impact of such related

person transaction on such outside director’s independence and the Company’s continued compliance with the requirements

under the Exchange Act, NASDAQ rules, or other applicable rules, laws and regulations.

Transactions with Deutsche Telekom

Certain of the related person transactions with Deutsche Telekom or its affiliates described below were not required to be approved in

accordance with our current Related Person Transaction Policy because they were entered into prior to or in connection with the

consummation of the Metro Combination, at which time Deutsche Telekom became a “related person” and our current Related Person

Transaction Policy became effective to such persons.

STOCKHOLDERS’ AGREEMENT

Pursuant to the Second Amended and Restated Stockholders’ Agreement we entered into with Deutsche Telekom and SoftBank on

June 22, 2020 (the “Stockholders’ Agreement”), we granted certain governance and other rights to Deutsche Telekom and SoftBank,

and each of Deutsche Telekom and SoftBank agreed to certain restrictions. In September 2021, the Stockholders’ Agreement generally

terminated with respect to SoftBank (except with respect to certain surviving provisions, including with respect to indemnification and

contribution) when SoftBank ceased to hold at least 5% of the voting percentage of the outstanding stock of the Company. The

Stockholders’ Agreement will also terminate with respect to Deutsche Telekom at any time Deutsche Telekom no longer holds at least

5% of the voting percentage of the outstanding stock of the Company.

The rights and restrictions applicable to Deutsche Telekom under the Stockholders’ Agreement are further outlined below:

• Under the Stockholders’ Agreement, at all times when the sum of the collective voting percentage of Deutsche Telekom,

SoftBank and Marcelo Claure is 50% or more, Deutsche Telekom can designate up to 10 nominees for election to our Board.

• So long as Deutsche Telekom beneficially owns 30% or more of the outstanding shares of our common stock, without

Deutsche Telekom’s consent, we are not permitted to take certain actions, including the incurrence of debt (excluding certain

permitted debt) if our consolidated ratio of debt to cash flow for the most recently ended four f ull fiscal quarters for which

financial statements are available would exceed 5.25 to 1.0 on a pro forma basis, the acquisition of any business, debt or

equity interests, operations or assets of any person for consideration in excess of $1 billion, the sale of any of the Company’s

or its subsidiaries’ divisions, businesses, operations or equity interests for consideration in excess of $1 billion, any change in

the size of our Board, the issuances of equity securities in excess of 10% of our outstanding shares or for the purpose of

redeeming or purchasing debt held by Deutsche Telekom, the repurchase or redemption of equity securities or the declaration

of extraordinary or in-kind dividends or distributions other than on a pro rata basis, or the termination or hiring of our Chief

Executive Officer.

• We must notify Deutsche Telekom any time it is reasonably likely that we will default on any indebtedness with a principal

amount greater than $75 million, and Deutsche Telekom will have the right, but not the obligation, to provide us with new debt

financing up to the amount of the indebtedness that is the subject of the potential default plus any applicable prepayment or

other penalties, on the same terms and conditions as such indebtedness (together with any waiver of the potential default).

• As long as Deutsche Telekom beneficially owns 10% or more of the outstanding shares of our common stock, we must provide

Deutsche Telekom with certain information and consultation rights, subject to certain confidentiality restrictions.

• Deutsche Telekom may not support, enter into or vote in favor of any transaction in excess of $120,000 in the aggregate

between or involving both us and Deutsche Telekom or any of its affiliates, or any amendment or modification to, extension or

waiver of, or statement of work under, any such transaction, without the approval of our Audit Committee.

• In the event that Deutsche Telekom’s voting percentage would be reduced to less than 30% as a direct result of a dilutive

issuance, Deutsche Telekom will have the right to acquire newly issued voting securities issued from us up to an amount that

would cause Deutsche Telekom’s voting percentage to equal its voting percentage prior to the dilutive issuance.

• Deutsche Telekom and its affiliates are generally prohibited from acquiring our common stock if such acquisition would cause

their collective beneficial ownership to exceed a certain percentage of the outstanding shares of our common stock unless

they make an offer to acquire all of the then-remaining outstanding shares of our common stock at the same price and on the

same terms and conditions as the proposed acquisition from all other stockholders of the Company, which is either

(i) accepted or approved by the majority of the directors, which majority includes a majority of non-affiliated directors or

(ii) accepted or approved by holders of a majority of our common stock held by stockholders other than Deutsche Telekom and

its affiliates.

• Deutsche Telekom is prohibited from transferring any shares of the Company’s common stock in any transaction that would

result in the transferee owning more than 30% of the outstanding shares of the Company’s common stock unless (i) such

transfer is approved by the majority of the directors or (ii) such transferee offers to acquire all of the then-outstanding shares of

the Company’s common stock at the same price and on the same terms and conditions as the proposed transfer.

• We have granted Deutsche Telekom certain demand and piggyback registration rights for shares of our common stock and

debt securities beneficially owned by Deutsche Telekom.

• Deutsche Telekom’s ability to compete with the Company in the United States, Puerto Rico and the territories and

protectorates of the United States is subject to certain restrictions during the period beginning on the date of the closing of

the Sprint Combination and ending on the date that is six months after the date on which Deutsche Telekom beneficially owns

less than 10% of the outstanding shares of the Company’s common stock. In addition, in the case of Deutsche Telekom, for

the period that commenced at the closing of the Sprint Combination and expires on the first anniversary of the termination of

the trademark license in accordance with its terms, Deutsche Telekom may not manufacture, market or distribute any products

territories and protectorates of the United States, (ii) a limited, non-exclusive, non-revocable and royalty-bearing license to use certain

other trademarks for use in connection with telecommunications and broadband products and services in the United States, Puerto

Rico and the territories and protectorates of the United States, and (iii) free of charge, the right to use the trademark “T-Mobile” as a

name for the Company.

In 2022, we paid Deutsche Telekom royalties totaling approximately $80.0 million under the terms of the trademark license. On the

fifth anniversary of the trademark license, the Company and Deutsche Telekom have agreed to adjust the royalty rate to the royalty rate

found under similar licenses for trademarks in the field of wireless telecommunication, broadband and information products and

services in the territory through a binding benchmarking process.

The Sprint Business Combination Agreement included a proposed “Amendment No. 1 to the License Agreement” by which the parties

agreed to a new royalty rate for the 10-year period commencing January 1, 2019, which retroactively took effect upon the successful

conclusion of the Sprint Combination on April 1, 2020. Under Amendment No. 1 to the License Agreement, we are obligated to pay

Deutsche Telekom a royalty in an amount equal to 0.25% (the “royalty rate”) of the net revenue (as defined in the trademark license)

generated by products and services sold by the Company under the licensed trademarks subject to a cap of $80 million per calendar

year through December 31, 2028. The trademark license contains certain quality control requirements, branding guidelines and

approval processes that the Company is obligated to maintain.

Deutsche Telekom is obligated to indemnify us against trademark infringement claims with respect to certain l icensed T-Mobile marks

and has the right (but not the obligation) to indemnify us against trademark infringement claims with respect to certain other licensed

trademarks. If Deutsche Telekom chooses not to defend us against trademark infringement claims with respect to certain other

licensed trademarks, we have the right to defend ourselves against such claims. We are obligated to indemnify Deutsche Telekom

against third-party claims due to the Company’s advertising or anti-competitive use by the Company of the licensed trademarks.

Except for indemnification obligations and intentional misconduct, the liability of the Company and Deutsche Telekom is limited to

€1 million per calendar year.

We and Deutsche Telekom are obligated to negotiate a new trademark license when (i) Deutsche Telekom has 50% or less of the

voting power of the outstanding shares of capital stock of the Company or (ii) any third party owns or controls, directly or indirectly,

50% or more of the voting power of the outstanding shares of capital stock of the Company, or otherwise has the power to direct or

cause the direction of the management and policies of the Company. If we and Deutsche Telekom fail to agree on a new trademark

license, either we or Deutsche Telekom may terminate the trademark license and such termination shall be effective, in the case of

clause (i) above, on the third anniversary after notice of termination and, in the case of clause (ii) above, on the second anniversary

after notice of termination. We have the right to continue to sell products under the licensed trademarks for a period of 12 months after

termination or expiration of the trademark license. Additionally, we have the right to continue to use advertising materials bearing the

licensed trademarks for a period of up to six months after termination or expiration of the trademark license.

of April 28, 2013, among T-Mobile USA, the Company, the other guarantors party thereto, and Deutsche Bank Trust Company

Americas, as trustee. The Indenture, as amended and supplemented with respect to the notes, contains covenants that, among other

things, restrict the ability of T-Mobile USA and its restricted subsidiaries to create liens or other encumbrances, and merge,

consolidate or sell, or otherwise dispose of, substantially all of their assets. The Indenture, as so amended and supplemented, also

contains customary events of default. These covenants and events of default are subject to a number of important qualifications and

exceptions.

Notes due 2028-1 held by Deutsche Telekom (collectively, the “Specified DT Notes”) have (or, in the case of notes that have been

repurchased, redeemed or matured, had) substantially the same terms and conditions as T-Mobile USA’s 4.000% Senior Notes due

2022, 5.375% Senior Notes due 2027 and 4.750% Senior Notes due 2028 issued in public offerings (collectively, the “Specified Public

Notes”), as applicable, other than issue date, registration rights, CUSIP, and, with respect to T-Mobile USA’s 5.375% Senior Notes due

2027-1, maturity. If T-Mobile USA exercises its rights in respect of Specified Public Notes, T-Mobile USA has agreed to exercise the

same rights under the corresponding Specified DT Notes on an equal and ratable basis.

Statement describes the proposals to be voted on at the Annual Meeting by the holders of record of our common stock on the record

date and includes information required to be disclosed to our stockholders.

HOW DO PROXIES WORK?

You may vote by authorizing the persons selected by us as your proxy to vote your shares at the Annual Meeting according to your

instructions on the matters discussed in this Proxy Statement, and according to their discretion on any other business that may

properly come before the Annual Meeting. We have designated two of our executive officers as proxies for the Annual Meeting: G.

Michael Sievert and Peter Osvaldik.

WHO IS ENTITLED TO VOTE?

If you are a holder of record of our common stock as of the record date (April 17, 2023), you may vote your shares on the matters to be

voted on at the Annual Meeting. You will receive only one proxy card for all the shares of common stock you hold in certificate and

book-entry form.

If, as of the record date, you hold shares of our common stock in “street name”—that is, through an account with a bank, broker or

other institution—you may direct the registered holder how to vote your shares at the Annual Meeting by following the instructions that

you will receive from the registered holder.

HOW DO I VOTE?

By Internet. Go to www.proxyvote.com, available 24 hours a day, seven days a week, and follow the on-screen instructions to submit

your proxy. You will need to have your proxy card available and use the Company number and account number shown on your proxy

card to cast your vote. This method of voting will be available until 11:59 p.m. Eastern Daylight Time, or EDT, on June 15, 2023, or the

date immediately before any date to which the Annual Meeting may be continued, adjourned or postponed.

By Mail. You may submit your proxy by mail by returning your executed proxy card. You should sign your proxy card using exactly the

same name as appears on the card, date your proxy card and indicate your voting preference on each proposal. You should mail your

proxy card with plenty of time in advance to allow for delivery prior to the Annual Meeting. Proxy cards received after 8:00 a.m. Pacific

Daylight Time on June 16, 2023 may not be considered unless the Annual Meeting is continued, adjourned or postponed and then

only if such proxy cards are received before the date and time the continued, adjourned or postponed Annual Meeting is held.

By Phone. You also may submit your proxy by phone from the United States and Canada, using the toll-free number on the proxy card

and the procedures and instructions described on the proxy card. Telephone voting will be considered at the Annual Meeting if

completed prior to 11:59 p.m. EDT on June 15, 2023, or the date immediately before any date to which the Annual Meeting may be

continued, adjourned or postponed.

At the Annual Meeting. You may also vote electronically at the virtual Annual Meeting. See “What do I need in order to virtually attend

the Annual Meeting?” below.

HOW ARE THE VOTES RECORDED? WHAT IS THE EFFECT IF I DO NOT VOTE?

• If you are a registered holder and we receive a valid proxy card from you by mail or receive your vote by phone or internet, your

shares will be voted by the named proxy holders as indicated in your voting preference selection.

• If you return your signed and dated proxy card without indicating your voting preference on one or more of the proposals to be

considered at the Annual Meeting, or if you otherwise do not indicate your voting preference via phone or internet on one or

more of the proposals to be considered at the Annual Meeting, your shares will be voted on the proposals for which you did

not indicate your voting preference in accordance with the recommendations of the Board.

PROXY STATEMENT 2023

Questions and Answers About the Annual Meeting and Voting

• If you hold your shares in street name and want your shares to be voted, you must instruct your broker, bank or other

institution how to vote such shares. Absent your specific instructions, NASDAQ rules do not permit brokers and banks to vote

your shares on a discretionary basis for non-routine corporate governance matters, such as the election of directors proposal

(resulting in a “broker non-vote”), but your shares can be voted without your instructions on the ratification of the appointment

of Deloitte & Touche LLP as our independent registered public accounting firm because this is considered a routine matter.

• If you indicate that you wish to withhold authority or abstain from voting on a proposal, your shares will not be voted and will

have no direct effect on the outcome of that proposal. Your shares, however, will count toward the quorum necessary to hold

the Annual Meeting.

* Under our bylaws, this proposal is decided by the vote of a majority of the votes cast in person (virtually) or by proxy at the Annual Meeting by the holders of our shares of common stock

entitled to vote thereon. Under this voting standard, this proposal will be approved if a majority of the votes cast “FOR” the proposal exceed the number of votes cast “AGAINST” the

proposal. Neither abstentions nor broker non-votes will count as votes cast “FOR” or “AGAINST” the proposal. Therefore, abstentions and broker non-votes, if any, will have no direct effect

on the outcome of the proposal.

** Broker non-votes are not expected for this proposal.

CAN I CHANGE MY VOTE OR REVOKE MY PROXY?

Yes. If you are a holder of record of our common stock, you may revoke your proxy at any time prior to the voting deadlines referred to

in “How do I vote?” above by:

• delivering a written revocation to our Corporate Secretary at our principal executive office located at 12920 SE 38th Street,

Bellevue, Washington 98006

• submitting another valid proxy card with a later date by mail;

• submitting another, later-dated proxy by phone or internet; or

• virtually attending the Annual Meeting and voting electronically.

Attendance at the virtual Annual Meeting will not, by itself, revoke a proxy.

If your shares are held in street name, you must contact your broker or other registered holder in order to revoke your previously

submitted voting instructions. Such revocation should be made sufficiently in advance of the Annual Meeting to ensure that the

revocation of the proxy card submitted by your registered holder is received by our Corporate Secretary prior to the date and time of

the Annual Meeting.

WHAT IS REQUIRED FOR A QUORUM AT THE ANNUAL MEETING?

To transact business at the Annual Meeting, a majority of the shares of our common stock issued and outstanding on the record date

and entitled to vote at the Annual Meeting must be present, in person (virtually) or by proxy, at the Annual Meeting. If a quorum is not

present at the Annual Meeting, no business can be transacted at that time, and the meeting will be continued, adjourned or

postponed to a later date. On the record date, there were 1,201,405,742 shares of our common stock outstanding and entitled to vote

at the Annual Meeting.

䡵

Questions and Answers About the Annual Meeting and Voting

A stockholder’s instruction to “withhold authority,” abstentions, and broker non-votes will be counted as present and entitled to vote at

the Annual Meeting for purposes of determining a quorum.

The Annual Meeting will again be held solely by means of remote communication, in a virtual only format. You will not be able to

related costs.

3. Other, net, primarily consists of certain severance, restructuring and other expenses and income, including gains from the sale of IP addresses, not directly attributable to the Merger which

are not reflective of T-Mobile’s core business activities (“special items”), and are, therefore, excluded from Adjusted EBITDA and Core Adjusted EBITDA.

Core Adjusted EBITDA and Adjusted EBITDA are non-GAAP financial measures utilized by T-Mobile’s management to monitor the

financial performance of our operations. T-Mobile historically used Adjusted EBITDA and T-Mobile currently uses Core Adjusted

EBITDA internally as a measure to evaluate and compensate its personnel and management for their performance. T-Mobile uses Core

Adjusted EBITDA and Adjusted EBITDA as benchmarks to evaluate T-Mobile’s operating performance in comparison to its

competitors. Management believes analysts and investors use Core Adjusted EBITDA and Adjusted EBITDA as supplemental measures

to evaluate overall operating performance and to f acilitate comparisons with other wireless communications services companies

because they are indicative of T-Mobile’s ongoing operating performance and trends by excluding the impact of interest expense from

financing, non-cash depreciation and amortization from capital investments, stock-based compensation, Merger-related costs,

including network decommissioning costs, impairment expense, losses on disposal groups held for sale and certain legal-related

recoveries and expenses, as well as other certain special income and expenses which are not reflective of T-Mobile’s core business

activities. Management believes analysts and investors use Core Adjusted EBITDA because it normalizes the transition in the

company’s device financing strategy, by excluding the impact of device lease revenues from Adjusted EBITDA, to align with the

exclusion of the related depreciation expense on leased devices from Adjusted EBITDA. Core Adjusted EBITDA and Adjusted EBITDA

have limitations as analytical tools and should not be considered in isolation or as a substitute for operating income, net income or

any other measure of financial performance reported in accordance with GAAP.

“Free Cash Flow”: Free cash flow is utilized by management, investors and analysts of our financial information to evaluate cash

available to pay debt, repurchase shares and provide further investment in the business. It represents Net cash provided by operating

activities less cash payments for Purchases of property and equipment, including Proceeds from sales of tower sites and Proceeds

related to beneficial interests in securitization transactions and less Cash payments for debt prepayment or debt extinguishment costs.

T-MOBILE US, INC.

2023 INCENTIVE AWARD PLAN

ARTICLE I.

PURPOSE

The Plan’s purpose is to enhance the Company’s ability to attract, retain and motivate highly qualified persons who make

(or are expected to make) important contributions to the Company by providing these individuals with an opportunity to acquire or

increase a direct proprietary interest in the operations and future success of the Company via equity ownership and/or equity-linked

compensation. Capitalized terms used in the Plan are defined in Article XI.

ARTICLE II.

ELIGIBILITY

Service Providers are eligible to be granted Awards under the Plan, subject to the limitations described herein.

ARTICLE III.

ADMINISTRATION AND DELEGATION

3.1 Administration. The Plan is administered by the Administrator. The Administrator has authority to determine which

Service Providers receive Awards, grant Awards and set Award terms and conditions, subject to the conditions and limitations in the

Plan. The Administrator also has the authority to take all actions and make all determinations under the Plan, to interpret the Plan and

Award Agreements and to adopt, amend and repeal Plan administrative rules, guidelines and practices as it deems advisable. The

Administrator may correct defects and ambiguities, supply omissions and reconcile inconsistencies in the Plan or any Award

Agreement as it deems necessary or appropriate to administer the Plan and any Awards. The Administrator’s determinations under the

Plan are in its sole discretion and will be final and binding on all persons having or claiming any interest in the Plan or any Award.

3.2 Appointment of Committees. To the extent Applicable Laws permit, the Board or the Administrator may delegate any

or all of its p owers under the Plan to one or more officers of the Company, Committees or committees of officers of the Company or

any of its Affiliates; provided, that in no event shall any officer of the Company be delegated the authority to grant Awards to, or amend

Awards held by, individuals who are subject to Section 16 of the Exchange Act or officers of the Company (or non-Employee Directors)

to whom the authority to grant or amend Awards has been delegated hereunder. The Board or the Administrator, as applicable, may

rescind any such delegation, abolish any such Committee or committee and/or re-vest in itself any previously delegated authority at

any time.

ARTICLE IV.

STOCK AVAILABLE FOR AWARDS

4.1 Number of Shares. Subject to adjustment under Article VIII and the terms of this Article IV, the maximum number of

Shares that may be issued pursuant to Awards under the Plan shall be equal to the Overall Share Limit. As of the Effective Date, no

new awards may be granted under the Prior Plans; however, Prior Plan Awards will remain subject to the terms and conditions of the

applicable Prior Plan. Shares issued under the Plan may consist of authorized but unissued Shares, Shares purchased on the open

market or treasury Shares.

4.2 Share Recycling. If all or any part of an Award expires, lapses or is terminated, exchanged for or settled in cash,

surrendered, repurchased, canceled without having been fully exercised/settled or forfeited, in any case, in a manner that results in

the Company acquiring Shares covered by the Award at a price not greater than the price (as adjusted to reflect any Equity

Restructuring) paid by the Participant for such Shares or not issuing any Shares covered by the Award, the unused Shares covered by

the Award will again be available for Award grants under the Plan. The p ayment of dividends or Dividend Equivalents in cash in

conjunction with any outstanding Awards shall not count against the Overall Share Limit. Notwithstanding anything to the contrary

contained herein, the following Shares shall not be added to the Shares authorized for grant under Section 4.1 and shall not be

䡵

PROXY STATEMENT 2023

ANXA-1

Annex A

available for future grants of Awards: (a) Shares tendered by a Participant or withheld by the Company to satisfy any tax withholding

obligation with respect to an Award; (b) Shares tendered by a Participant or withheld by the Company in payment of the exercise price

of an Option; (c) Shares subject to a Stock Appreciation Right that are not issued in connection with the stock settlement of the Stock

Appreciation Right on exercise thereof; and (d) Shares purchased on the open market with the cash proceeds from the exercise of

Options.

4.3 Incentive Stock Option Limitations. Notwithstanding anything to the contrary herein, no more than 24,000,000

Shares may be issued pursuant to the exercise of Incentive Stock Options.

4.4 Substitute Awards. In connection with an entity’s merger or consolidation with the Company or any Subsidiary or

the Company’s or any Subsidiary’s acquisition of an entity’s property or equity securities, the Administrator may grant Awards in

substitution for any options or other equity or equity-based awards granted before such merger or consolidation by such entity or its

affiliate. Substitute Awards may be granted on such terms as the Administrator deems appropriate, notwithstanding limitations on

Awards in the Plan. Substitute Awards will not count against the Overall Share Limit (nor shall Shares subject to a Substitute Award be

added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute

Incentive Stock Options will count against the maximum number of Shares that may be issued pursuant to the exercise of Incentive

Stock Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the

Company or any Subsidiary combines has equity securities available under a pre-existing plan approved by equityholders and not

adopted in contemplation of such acquisition or combination, the equity securities available for grant pursuant to the terms of such

pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula

used in such acquisition or combination to determine the consideration payable to the equityholders of the entities party to such

acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the

Plan (and Shares subject to such Awards shall not be added to the Shares available for Awards under the Plan as provided above);

provided that Awards using such available Shares shall not be made after the date awards or grants could have been made under the

terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Service

Providers prior to such acquisition or combination.

4.5 Individual Award Limits. Notwithstanding any provision to the contrary in the Plan, and subject to Article VIII, the

maximum aggregate number of Shares with respect to one or more Awards that may be granted to any one person during any twelve

(12)-month period shall be 2,000,000 Shares, and the maximum aggregate amount of cash that may be paid to any one person during

any twelve (12)-month period with respect to one or more Awards payable in cash shall be $25,000,000. The individual Award limits

set forth in this Section 4.5 are referred t o herein as the “Individual Award Limits”.

4.6 Non-Employee Director Compensation. Notwithstanding any provision to the contrary in the Plan, the Administrator

may establish compensation for non-Employee Directors from time to time, subject to the limitations in the Plan. The Administrator will

from time to time determine the terms, conditions and amounts of all such non-Employee Director compensation in its discretion and

pursuant to the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem

relevant from time to time; provided that, the sum of any cash compensation, or other compensation, and the value (determined as of

the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any

successor thereto) of Awards granted to a non-Employee Director as compensation for services as a non-Employee Director during any

fiscal year of the Company may not exceed $1,000,000 (the “Non-Employee Director Limit”).

ARTICLE V.

STOCK OPTIONS AND STOCK APPRECIATION RIGHTS

5.1 General. The Administrator may grant Options or Stock Appreciation Rights to Service Providers subject to the

limitations in the Plan, including any limitations in the Plan that apply to Incentive Stock Options. The Administrator will determine the

number of Shares covered by each Option and Stock Appreciation Right and the conditions and limitations applicable to the exercise

of each Option and Stock Appreciation Right. A Stock Appreciation Right will entitle the Participant (or other person entitled to

exercise the Stock Appreciation Right) to receive from the Company upon e xercise of the exercisable portion of the Stock Appreciation

Right an amount determined by multiplying the excess, if any, of the Fair Market Value of one Share on the date of exercise over the

exercise price per Share of the Stock Appreciation Right by the number of Shares with respect to which the Stock Appreciation Right

is exercised, subject to any limitations of the Plan or that the Administrator may impose, and payable in cash, Shares valued at Fair

Market Value or a combination of the two as the Administrator may determine or provide in the Award Agreement.

5.2 Exercise Price. The Administrator will establish each Option’s and Stock Appreciation Right’s exercise price and

specify the exercise price in the Award Agreement. Unless otherwise determined by the Administrator, the exercise price will not be

less than 100% of the Fair Market Value on the grant date of the Option (subject to Section 5.6) or Stock Appreciation Right.

ANXA-2

PROXY STATEMENT 2023

䡵

Annex A

Notwithstanding the foregoing, in the case of an Option or a Stock Appreciation Right that is a Substitute Award, the exercise price

per share of the Shares subject to such Option or Stock Appreciation Right, as applicable, may be less than the Fair Market Value per

share on the date of grant; provided that the exercise price of any Substitute Award shall be determined in accordance with the

applicable requirements of Sections 424 and 409A of the Code.

5.3 Duration. Each Option or Stock Appreciation Right will be exercisable at such times and as specified in the Award

Agreement, provided that, subject to Section 5.6, the term of an Option or Stock Appreciation Right will not exceed ten years.

Notwithstanding the foregoing and unless determined otherwise by the Company, in the event that on the last business day of the

term of an Option or Stock Appreciation Right (other than an Incentive Stock Option) (i) the exercise of the Option or Stock

Appreciation Right is prohibited by Applicable Law, as determined by the Company, or (ii) Shares may not be purchased or sold by

the applicable Participant due to any Company insider trading policy (including blackout periods) or a “lock-up” agreement

undertaken in connection with an issuance of securities by the Company, the term of the Option or Stock Appreciation Right shall be

automatically extended until the date that is 30 days after the end of the legal prohibition, black-out period or lock-up agreement, as

determined by the Company; provided, however, in no event shall the extension last beyond the ten year term (or any shorter

maximum, if applicable) of the applicable Option or Stock Appreciation Right. Notwithstanding the foregoing, to the extent permitted

under Applicable Laws, if the Participant, prior to the end of the term of an Option or Stock Appreciation Right, violates the

non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract,

confidentiality and nondisclosure agreement or other agreement between the Participant and the Company or any of its Affiliates, the

right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant

shall terminate immediately upon such violation, unless the Company otherwise determines.

5.4 Exercise. Options and Stock Appreciation Rights may be exercised by delivering to the Company (or its Agent) a

written notice of exercise, in a form the Administrator approves (which may be electronic and provided through the online platform

maintained by an Agent), signed by the p erson authorized to exercise the Option or Stock Appreciation Right, together with, as

applicable, payment in full (i) as specified in Section 5.5 for the number of Shares for which the Award is exercised and (ii) as

specified in Section 9.5 for any applicable taxes. Unless the Administrator otherwise determines, an Option or Stock Appreciation

Right may not be exercised for a fraction of a Share.

5.5 Payment Upon Exercise. Subject to Section 10.8, any Company insider trading policy (including blackout periods)

and Applicable Laws, the exercise price of an Option must be paid by online payment through the Agent’s electronic platform or by

wire transfer of immediately available funds to the Agent (or, in each case, if the Company has no Agent accepting payment, by wire

transfer of immediately available funds to the Company) or, solely to the extent set forth in the applicable Award Agreement or

otherwise with the consent of the Administrator, by:

(a) cash, wire transfer of immediately available funds or check payable to the order of the Company, provided

that the Administrator may limit the use of one of the foregoing payment forms if one or more of the payment forms below is permitted;

(b) if there is a public market for Shares at the time of exercise, unless the Administrator otherwise determines,

(A) delivery (including electronically or telephonically to the extent permitted by the Administrator) of an irrevocable and unconditional

undertaking by a broker acceptable to the Administrator to deliver promptly to the Company sufficient funds to pay the exercise price,

or (B) the Participant’s delivery to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the

Administrator to deliver promptly to the Company cash or a check sufficient to pay the exercise price; provided that such amount is

paid to the Company at such time as may be required by the Administrator;

Market Value;

(d) surrendering Shares then issuable upon the Option’s exercise valued at their Fair Market Value on the

exercise date;

(e) delivery of a promissory note or any other property that the Administrator determines is good and valuable

consideration; or

(f) any combination of the above payment forms approved by the Administrator.

5.6 Additional Terms of Incentive Stock Options. The Administrator may grant Incentive Stock Options only to

employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the

Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code. If an

Incentive Stock Option is granted to a Greater Than 10% Stockholder, the exercise price will not be less than 110% of the Fair Market

Value on the Option’s grant date, and the term of the Option will not exceed five years. All Incentive Stock Options will be subject to

and construed consistently with Section 422 of the Code. By accepting an Incentive Stock Option, the Participant agrees to give

䡵

PROXY STATEMENT 2023

Annex A

prompt notice to the Company of dispositions or other transfers (other than in connection with a Change in Control) of Shares

acquired under the Option made within (i) two years from the grant date of the Option or (ii) one year after the transfer of such Shares

to the Participant, specifying the date of the disposition or other transfer and the amount the Participant realized, in cash, other

property, assumption of indebtedness or other consideration, in such disposition or other transfer. Neither the Company nor the

Administrator will be liable to a Participant, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive

stock option” under Section 422 of the Code. Any Incentive Stock Option or portion thereof that fails to qualify as an “incentive stock

option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares having a fair market

value exceeding the $100,000 limitation under Treasury Regulation Section 1.422-4, will be a Non-Qualified Stock Option.

5.7 No Dividends or Dividend Equivalents. No dividends or Dividend Equivalents shall be payable with respect to

Options or Stock Appreciation Rights.

ARTICLE VI.

RESTRICTED STOCK; RESTRICTED STOCK UNITS

6.1 General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any Service

Provider, subject to the Company’s right to repurchase all or part of such Shares at their issue price or other stated or formula price

from the Participant (or to require forfeiture of such Shares) if conditions the Administrator specifies in the Award Agreement are not

satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition,

the Administrator may grant Restricted Stock Units to any Service Provider, which may be subject to vesting and forfeiture conditions

during the applicable restriction period or periods, as set forth in an Award Agreement. The Administrator will determine and set forth

in the Award Agreement the terms and conditions for each Restricted Stock and Restricted Stock Unit Award, subject to the

conditions and limitations contained in the Plan.

6.2 Restricted Stock.

(a) Dividends. Participants holding Shares of Restricted Stock will be entitled to all ordinary cash dividends

paid with respect to such Shares, unless the Administrator provides otherwise in the Award Agreement. In addition, unless the

Administrator provides otherwise, if any dividends or distributions are paid in Shares, or consist of a dividend or distribution to

holders of Common Stock of property other than an ordinary cash dividend, the Shares or other property will be subject to the same

restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. Notwithstanding

anything to the contrary herein, with respect to any award of Restricted Stock, dividends which are paid to holders of Common Stock

prior to vesting shall only be paid out to the Participant holding such Restricted Stock to the extent that the vesting conditions are

subsequently satisfied. All such dividend payments will be made no later than March 15 of the calendar year following the calendar

year in which the right to the dividend payment becomes nonforfeitable.

(b) Stock Certificates. The Company may require that the Participant deposit in escrow with the Company (or

its designee) any stock certificates issued in respect of Shares of Restricted Stock, together with a stock power endorsed in blank.

6.3 Restricted Stock Units.

(a) Settlement. The Administrator may provide that settlement of Restricted Stock Units will occur upon or as

soon as reasonably practicable after the Restricted Stock Units vest or will instead be deferred, on a mandatory basis or at the

Participant’s election, in a manner intended to comply with Section 409A. Restricted Stock Units may be settled in cash or Shares, as

determined by the Administrator and set forth in the applicable Award Agreement.

(b) Stockholder Rights. A Participant will have no rights of a stockholder with respect to Shares subject to any

Restricted Stock Unit unless and until the Shares are delivered in settlement of the Restricted Stock Unit.

shall only be paid out to the Participant to the extent that the vesting conditions applicable to the underlying Award are satisfied. All

such Dividend Equivalent payments will be made no later than March 15 of the calendar year following calendar year in which the

right to the Dividend Equivalent payment becomes nonforfeitable in accordance with the foregoing, unless otherwise determined by

the Administrator or unless deferred in a manner intended to comply with Section 409A.

ARTICLE VII.

OTHER STOCK OR CASH BASED AWARDS; DIVIDEND EQUIVALENTS

7.1 Other Stock or Cash Based Awards. Other Stock or Cash Based Awards may be granted to Participants, including

Awards entitling Participants to receive Shares to be delivered in the future and including annual or other periodic or long-term cash

ANXA-4

PROXY STATEMENT 2023

䡵

Annex A

bonus awards (whether based on specified Performance Criteria or otherwise), in each case subject to any conditions and limitations

in the Plan. Such Other Stock or Cash Based Awards will also be available as a payment form in the settlement of other Awards, as

standalone payments and as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock or Cash Based

Awards may be paid in Shares, cash or other property, or any combination of the foregoing, as the Administrator determines. Subject

to the provisions of the Plan, the Administrator will determine the terms and conditions of each Other Stock or Cash Based Award,

including any purchase price, performance goal(s) (which may be based on the Performance Criteria), transfer restrictions, and vesting

conditions, which will be set forth in the applicable Award Agreement. In addition, the Company may adopt subplans or programs

under the Plan pursuant to which it makes Awards available in a manner consistent with the terms and conditions of the Plan.

7.2 Dividend Equivalents. A grant of Restricted Stock Units or Other Stock or Cash Based Award may provide a Participant

with the right to receive Dividend Equivalents, and no dividends or Dividend Equivalents shall be payable with respect to Options or Stock

Appreciation Rights. Dividend Equivalents may be paid currently or credited to an account for the Participant, settled in cash or Shares and

subject to the same restrictions on transferability and forfeitability as the Award with respect to which the Dividend Equivalents are paid

and subject to other terms and conditions as set forth in the Award Agreement. Notwithstanding anything to the contrary herein, Dividend

Equivalents with respect to an Award shall only be paid out to the Participant to the extent that the vesting conditions applicable to the

underlying Award are satisfied. All such Dividend Equivalent payments will be made no later than March 15 of the calendar year following

calendar year in which the right to the Dividend Equivalent payment becomes nonforfeitable in accordance with the foregoing, unless

otherwise determined by the Administrator or unless deferred in a manner intended to comply with Section 409A.

ARTICLE VIII.

ADJUSTMENTS FOR CHANGES IN COMMON STOCK

AND CERTAIN OTHER EVENTS

8.1 Equity Restructuring. In connection with any Equity Restructuring, notwithstanding anything to the contrary in this

Article VIII, the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring,

which may include adjusting the number and type of securities subject to each outstanding Award and/or the Award’s exercise price

or grant price (if applicable), granting new Awards to Participants, and/or making a cash payment to Participants. The adjustments

provided under this Section 8.1 will be nondiscretionary and final and binding on the affected Participant and the Company; provided

that the Administrator will determine whether an adjustment is equitable.

8.2 Corporate Transactions. Subject to Section 8.3, in the event of any dividend or other distribution (whether in the

form of cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation,

repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the

assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of

warrants or other rights to purchase Common Stock or other securities of the Company, other similar corporate transaction or event,

other unusual or nonrecurring transaction or event affecting the Company or its financial statements or any change in any Applicable

Laws or accounting principles, the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the

Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in

Applicable Law or accounting principles may be made within a reasonable period of time after such change), is hereby authorized to

take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to

(x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan

or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such

changes in Applicable Laws or accounting principles:

(a) To provide for the cancellation of any such Award in exchange for either an amount of cash or other

property with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such

Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that

could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights,

in any case, is equal to or less than zero, then the Award may be terminated without payment;

(b) To provide that such Award shall vest and, to the extent applicable, be exercisable as to all Shares covered

thereby, notwithstanding anything to the contrary in the Plan or the provisions of such Award;

thereof, or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary

thereof, with appropriate adjustments as to the number and kind of shares and/or applicable exercise or purchase price, in all cases,

as determined by the Administrator;

䡵

PROXY STATEMENT 2023

ANXA-5

Annex A

(d) To make adjustments in the number and type of Shares (or other securities or property) subject to

outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of

the limitations in Article IV on the maximum number and kind of shares which may be issued) and/or in the terms and conditions of

(including the grant or exercise price or applicable performance goals), and the criteria included in, outstanding Awards;

(e) To replace such Award with other rights or property selected by the Administrator; and/or

(f) To provide that the Award will terminate and cannot vest, be exercised or become payable after the

applicable event.

8.3 Effect of a Change in Control. Notwithstanding the provisions of Section 8.2, if a Change in Control occurs,

outstanding Awards shall be treated as follows:

(a) With respect to any Award held by a non-Employee Director, and provided that such non-Employee Director

has not had a Termination of Service prior to such Change in Control, effective immediately prior to the Change in Control, such

Award shall become fully vested, exercisable and/or payable, as applicable, all forfeiture, repurchase and other restrictions on such

Award shall lapse, and any specified performance goals with respect to outstanding Awards shall be deemed to be satisfied at the

greater of (i) target or (ii) the actual level of performance determined as if the applicable performance period had ended as of (x) the

last trading day immediately preceding the Change in Control or (y) if determined by the Administrator to be necessary or appropriate

based on the applicable performance goal, as of another specified date preceding the Change in Control (in either case, the

“Measurement Date”).

(b) With respect to any Award held by any Service Provider who is not a non-Employee Director that is not

continued, converted, assumed, or replaced with a substantially similar award by (i) the Company, or (ii) a successor entity or its

parent or subsidiary (an “Assumption”), and provided that such Service Provider has not had a Termination of Service prior to such

Change in Control, effective immediately prior to the Change in Control, such Award shall become fully vested, exercisable and/or

payable, as applicable, and all forfeiture, repurchase and other restrictions on such Award shall lapse; provided, that with respect to

any Awards that, as of immediately prior to such Change in Control, are subject to performance-based vesting, (x) any specified

performance goals shall be deemed to be satisfied at the greater of (A) target or (B) the actual level of performance determined as if

the applicable performance period had ended as of the Measurement Date, and (y) the actual number of Shares subject to such

Awards that become vested, exercisable and/or payable, as applicable, shall be pro-rated.

to an Assumption upon a Change in Control, if, within one year a fter the date of such Change in Control, the Service Provider incurs a

Termination of Service either (i) by the Company other than for Cause or (ii) by the Service Provider for Good Reason, then such

Award shall become fully vested, exercisable and/or payable, as applicable, all forfeiture, repurchase and other restrictions on such

Award shall lapse, and any specified performance goals with respect to such Award shall be deemed to be satisfied at the greater of

(x) target or (y) the actual level of performance determined as if the applicable performance period had ended as of the Measurement

Date.

(d) Any Award that is subject to Section 8.3(a) or (b) above shall be canceled upon the consummation of the

Change in Control in exchange for the right to receive the Change in Control consideration payable to holders of Shares (i) which may

be on such terms and conditions as apply generally to holders of Shares under the Change in Control documents (including, without

limitation, any escrow, earn-out or other deferred consideration provisions) or such other terms and conditions as the Administrator

may provide, and (ii) determined by reference to the number of Shares subject to such Award and net of any applicable exercise price;

provided that to the extent that any Award constitutes “nonqualified deferred compensation” that may not be paid upon the Change in

Control under Section 409A (to the extent applicable to such Award) without the imposition of taxes thereon under Section 409A, the

timing of such payments shall be governed by the applicable Award Agreement (subject to any deferred consideration provisions

applicable under the Change in Control documents); and provided, further, that if the amount to which the Participant would be

entitled upon the settlement or exercise of such Award at the time of the Change in Control is equal to or less than zero, then such

Award may be terminated without payment. The Administrator shall determine whether an Assumption of an Award h as occurred in

connection with a Change in Control.

8.4 Administrative Stand Still. In the event of any pending stock dividend, stock split, combination or exchange of

shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other

extraordinary transaction or change affecting the Shares or the share price of Common Stock, including any Equity Restructuring or

any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the exercise

of any Award for up to 60 days before or after such transaction.

Annex A

8.5 General. Except as expressly provided in the Plan or the Administrator’s action under the Plan, no Participant will

have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number

of Shares of any class or dissolution, liquidation, merger, or consolidation of the Company or other corporation. Except as expressly

provided with respect to an Equity Restructuring under Section 8.1 or the Administrator’s action under the Plan, no issuance by the

Company of Shares of any class, or securities convertible into Shares of any class, will affect, and no adjustment will be made

regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award

Agreements and the Awards granted hereunder will not affect or restrict in any way the Company’s right or power to make or authorize

(i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, (ii) any merger,

consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including

securities with rights superior to those of the Shares or securities convertible into or exchangeable for Shares. The Administrator may

treat Participants and Awards (or portions thereof) differently under this Article VIII.

ARTICLE IX.

GENERAL PROVISIONS APPLICABLE TO AWARDS

9.1 Transferability. Except as the Administrator may determine or provide in an Award Agreement or otherwise for

Awards other than Incentive Stock Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either

voluntarily or by operation of law, except for certain beneficiary designations, by will or the laws of descent and distribution, or,

subject to the Administrator’s consent, p ursuant to a domestic relations order, and, during the life of the Participant, will be

exercisable only by the Participant. Any permitted transfer of an Award hereunder shall be without consideration, except as required

by Applicable Law. References to a Participant, to the extent relevant in the context, will include references to a Participant’s

authorized transferee that the Administrator specifically approves.

9.2 Documentation. Each Award will be evidenced in an Award Agreement, which may be written or electronic, as the

Administrator determines. The Award Agreement will contain the terms and conditions applicable to an Award. Each Award may

contain terms and conditions in addition to those set forth in the Plan.

9.3 Discretion. Except as the Plan otherwise provides, each Award may be made alone or in addition or in relation to

any other Award. The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or

Awards (or portions thereof) uniformly.

9.4 Termination of Status. The Administrator will determine how a Participant’s Disability, death, retirement or

authorized leave of absence or any other change or purported change in a Participant’s Service Provider status affects an Award

(including whether and when a Termination of Service has occurred) and the extent to which, and the period during which the

Participant, the Participant’s legal representative, conservator, guardian or Designated Beneficiary may exercise rights under the

Award, if applicable.

9.5 Withholding. Each Participant must pay the Company, or make provision satisfactory to the Administrator for

payment of, any taxes required by Applicable Law to be withheld in connection with such Participant’s Awards by the date of the

event creating the tax liability. The Company or one of its Affiliates may deduct an amount sufficient to satisfy such tax obligations

based on the applicable statutory withholding rates (or such other rate as may be determined by the Administrator after considering

any accounting consequences or costs) from any payment of any kind otherwise due to a Participant. Subject to Section 10.8 and any

Company insider trading policy (including blackout periods), Participants may satisfy such tax obligations through the Agent’s

electronic platform or by wire transfer of immediately available funds to the Agent (or, in each case, if the Company has no Agent

accepting payment, by wire transfer of immediately available funds to the Company) or, solely with the consent of the Administrator, by

(i) cash, wire transfer of immediately available funds or check made payable to the order of the Company, provided that the

Administrator may limit the use of the foregoing payment forms in its discretion, (ii) to the extent permitted by the Administrator,

delivery of Shares (in whole or in part), including Shares delivered by attestation and Shares retained from the Award creating the tax

obligation, (iii) if there is a public market for Shares at the time the tax obligations are satisfied, unless the Administrator otherwise

determines, (A) delivery (including electronically or telephonically to the extent permitted by the Administrator) of an irrevocable and

unconditional undertaking by a broker acceptable to the Administrator to deliver promptly to the Company sufficient funds to satisfy

the tax obligations, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a

broker acceptable to the Administrator to deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding;

provided that such amount is paid to the Company at such time as may be required by the Administrator, or (iv) to the extent

permitted by the Administrator, any combination of the foregoing payment forms approved by the Administrator. Notwithstanding any

other provision of the Plan, the number of Shares which may be so delivered or retained pursuant to clause (ii) of the immediately

preceding sentence shall be no greater than the number of Shares which have a Fair Market Value no greater than the aggregate

amount of such liabilities based on the maximum individual statutory tax rate in the applicable jurisdiction (or based on such other

䡵

PROXY STATEMENT 2023

ANXA-7

Annex A

rate as may be required to avoid the liability classification of the applicable award under generally accepted accounting principles in

the United States of America or as otherwise may be set forth in the applicable Award Agreement or determined by the Administrator),

and for clarity, may be less than such maximum individual statutory tax rate if so determined by the Administrator. If any tax

withholding obligation will be satisfied under clause (ii) above by the Company’s retention of Shares from the Award creating the tax

obligation and there is a public market for Shares at the time the tax obligation is satisfied, the Company may elect to instruct any

brokerage firm determined acceptable to the Company for such purpose to sell on the applicable Participant’s behalf some or all of the

Shares retained and to remit the proceeds of the sale to the Company or its designee, and e ach Participant’s acceptance of an Award

under the Plan will constitute the Participant’s authorization to the Company and instruction and authorization to such brokerage firm

to complete the transactions described in this sentence.

9.6 Amendment of Award. The Administrator may amend, modify or terminate any outstanding Award, including by

substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive

Stock Option to a Non-Qualified Stock Option. The Participant’s consent to such action will be required unless (i) the action, taking

into account any related action, does not materially and adversely affect the Participant’s rights under the Award, or (ii) the change is

permitted under Article VIII or pursuant to Section 10.6.

9.7 Conditions on Delivery of Stock. The Company will not be obligated to deliver any Shares under the Plan or remove

restrictions from Shares previously delivered under the Plan until (i) all Award conditions have been met or removed to the Company’s

satisfaction, (ii) as determined by the Company, all other legal matters regarding the issuance and delivery of such Shares have been

satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant

has executed and delivered to the Company such representations or agreements as the Administrator deems necessary or appropriate

to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which the

Administrator determines is necessary to the lawful issuance and sale of any securities, will relieve the Company of any liability for

failing to issue or sell such Shares as to which such requisite authority has not been obtained.

9.8 Acceleration. The Administrator may at any time provide that any Award will become immediately vested and fully or

partially exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable.

9.9 Cash Settlement. Without limiting the generality of any other provision of the Plan, the Administrator may provide, in

an Award Agreement or subsequent to the grant of an Award, in its discretion, that any Award may be settled in cash, Shares or a

combination thereof.

9.10 Broker-Assisted Sales. In the event of a broker-assisted sale of Shares in connection with the payment of amounts

owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of

Section 9.5: (i) any Shares to be sold through the broker-assisted sale will be sold on the day the payment first becomes due, or as

soon thereafter as practicable; (ii) such Shares may be sold as part of a block trade with other Participants in the Plan in which all

participants receive an average price; (iii) the applicable Participant will be responsible for all broker’s fees and other costs of sale,

and by accepting an Award, each Participant agrees to indemnify and hold the Company and its Affiliates harmless from any losses,

costs, damages, or expenses relating to any such sale; (iv) to the extent the Company, its Affiliates or their designee receives proceeds

of such sale that exceed the amount owed, the Company or its Affiliate will pay such excess in cash to the applicable Participant as

soon as reasonably practicable; (v) the Company, its Affiliates and their designees are under no obligation to arrange for such sale at

any particular price; and (vi) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable obligation,

the Participant may be required to pay immediately upon demand to the Company, its Affiliates or their designee an amount in cash

sufficient to satisfy any remaining portion of the Participant’s obligation.

9.12 Prohibition on Repricing. Except pursuant to Article VIII, the Administrator shall not, without the approval of the

Company’s shareholders, (a) reduce, whether through amendment or otherwise, the exercise price of any outstanding Option or Stock

Appreciation Right, or (b) grant any new Award or make any payment of cash in substitution for or upon the cancellation of Options

and/or Stock Appreciation Rights previously granted when the exercise price of such Option or Stock Appreciation Right exceeds the

Fair Market Value of the underlying Shares.

ARTICLE X.

MISCELLANEOUS

10.1 No Right to Employment or Other Status. No person will have any claim or right to be granted an Award, and the

grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the

Company or any of its Affiliates. The Company and its Affiliates expressly reserve the right at any time to dismiss or otherwise

terminate their respective relationships with a Participant free from any liability or claim under the Plan or any Award, except as

expressly provided in an Award Agreement.

Annex A

10.2 No Rights as Stockholder; Certificates. Subject to the Award Agreement, no Participant or Designated Beneficiary

will have any rights as a stockholder with respect to any Shares to be distributed under an Award until becoming the record holder of

such Shares. Notwithstanding any other provision of the Plan, unless the Administrator otherwise determines or Applicable Laws

require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any

Award and instead such Shares may be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan

administrator). The Company may place legends on stock certificates issued under the Plan that the Administrator deems necessary or

appropriate to comply with Applicable Laws.

10.3 Effective Date and Term of Plan. Unless earlier terminated by the Board, the Plan will become effective on the date

on which the Company’s stockholders approve the Plan (the “ Effective Date”) and will remain in effect until the tenth anniversary of

the Effective Date, but Awards previously granted may extend beyond that date in accordance with the Plan. Notwithstanding anything

to the contrary in the Plan, an Incentive Stock Option may not be granted under the Plan after 10 years from the earlier of (i) the date

the Board adopted the Plan or (ii) the date the Company’s stockholders approved the Plan. If the Plan is not approved by the

Company’s stockholders, the Plan will not become effective, no Awards will be granted under the Plan and the Prior Plans will

continue in full force and effect in accordance with their terms.

10.4 Amendment of Plan. The Board may amend, suspend or terminate the Plan at any time; provided that no

amendment, other than (a) as permitted by the applicable Award Agreement, (b) as provided under Sections 10.6 and 10.15, or (c) an

amendment to increase the Overall Share Limit, may materially and adversely affect any Award outstanding at the time of such

amendment without the affected Participant’s consent. No Awards may be granted under the Plan during any suspension period or

after the Plan’s termination. Awards outstanding at the time of any Plan suspension or termination will continue to be governed by the

Plan and the Award Agreement, as in effect before such suspension or termination. The Board will obtain stockholder approval of any

Plan amendment (i) to increase the Non-Employee Director Limit or the Individual Award Limits, (ii) to Section 9.12 of the Plan, or

(iii) to the extent necessary to comply with Applicable Laws.

10.5 Provisions for Foreign Participants. The Administrator may modify Awards granted to Participants who are foreign

nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in laws,

rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters.

10.6 Section 409A.

(a) General. To the extent that the Administrator determines that any Award granted under the Plan is subject

to Section 409A, the Award Agreement evidencing such Award shall incorporate the terms and conditions required by Section 409A.

To the extent applicable, the Plan and the Award Agreements shall be interpreted in accordance with Section 409A, such that no

adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award

Agreement to the contrary, the Administrator may, without a Participant’s consent, amend this Plan or Awards, adopt policies and

procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or

appropriate to preserve the intended tax treatment of Awards, including any such actions intended to (A) exempt this Plan or any

Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other

interpretative authority that may be issued after an Award’s grant date. The Company makes no representations or warranties as to an

Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 10.6 or otherwise to

avoid the taxes, penalties or interest under Section 409A with respect to any Award and will have no liability to any Participant or any

other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant “nonqualified

deferred compensation” subject to taxes, penalties or interest under Section 409A. Notwithstanding any contrary provision of the Plan

or any Award Agreement, any payment of “nonqualified deferred compensation” under the Plan that may be made in installments shall

be treated as a right to receive a series of separate and distinct payments.

(b) Separation from Service. If an Award is subject to and constitutes “nonqualified deferred compensation”

under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will,

to the extent necessary to avoid taxes under Section 409A, be made only upon the P articipant’s “separation from service” (within the

meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the Participant’s Service

Provider relationship. For purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a

“termination,” “termination of employment” or like terms means a “separation from service.”

Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award subject to Section 409A to

a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his or her “separation from

service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six-month period

immediately following such “separation from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as

䡵

PROXY STATEMENT 2023

ANXA-9

Annex A

set forth in the Award Agreement) on the day immediately following such six-month period or as soon as administratively practicable

thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six months

following the Participant’s “separation from service” will be paid at the time or times the payments are otherwise scheduled to be

made.

10.7 Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director,

officer, other employee or agent of the Company or any Affiliate will be liable to any Participant, former Participant, spouse,

beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan or any Award, and such

individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her

capacity as an Administrator, director, officer, other employee or agent of the Company or any Affiliate. The Company will indemnify

and hold harmless each director, officer, other employee and agent of the Company or any Affiliate that has been or will be granted or

delegated any duty or power relating to the Plan’s administration or interpretation, against any cost or expense (including attorneys’

fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising from any act or omission

concerning this Plan unless arising from such person’s own fraud or bad faith.

10.8 Lock-Up Period. The Company may, at the request of any underwriter representative or otherwise, in connection

with registering the offering of any Company securities under the Securities Act, prohibit Participants from, directly or indirectly,

selling or otherwise transferring any Shares or other Company securities during a period of up to 180 days following the effective date

of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter.

10.9 Data Privacy. As a condition for receiving any Award, each Participant explicitly and unambiguously consents to the

collection, use and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its

Affiliates exclusively for implementing, administering and managing the Participant’s participation in the Plan. The Company and its

Affiliates may hold certain personal information about a Participant, including the Participant’s name, address and telephone number;

birthdate; social security number, insurance number or other identification number; salary; nationality; job title(s); any Shares held in the

Company or its Affiliates; and Award details, to implement, manage and administer the Plan and Awards (the “Data”). The Company and

its Affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage a Participant’s participation in

the Plan, and the Company and its Affiliates may transfer the Data to third parties assisting the Company with Plan implementation,

administration and management. These recipients may be located in the Participant’s country, or elsewhere, and the Participant’s country

may have different data privacy laws and protections than the recipients’ country. By accepting an Award, each Participant authorizes

such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage

the Participant’s participation in the Plan, including any required Data transfer to a broker or other third party with whom the Company or

the Participant may elect to deposit any Shares. The Data related to a Participant will be held only as long as necessary to implement,

administer, and manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data that the Company and its

Affiliates hold regarding such Participant, request additional information about the storage and processing of the Data regarding such

Participant, recommend any necessary corrections to the Data regarding the Participant or refuse or withdraw the consents in this

Section 10.9 in writing, without cost, by contacting the local human resources representative. If the Participant refuses or withdraws the

consents in this Section 10.9, the Company may cancel Participant’s ability to participate in the Plan and, in the Administrator’s

discretion, the Participant may forfeit any outstanding Awards. For more information on the consequences of refusing or withdrawing

consent, Participants may contact their local human resources representative.

10.10 Severability. If any portion of the Plan or any action taken under it is held illegal or invalid for any reason, the

illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or

invalid provisions had been excluded, and the illegal or invalid action will be null and void.

10.11 Governing Documents. If any contradiction occurs between the Plan and any Award Agreement or other written

agreement between a Participant and the Company (or any Affiliate) that the Administrator has approved, the Plan will govern, unless

it is expressly specified in such Award Agreement or other written document that the specific provision of the Plan will not apply. For

clarity, the foregoing sentence shall not limit the applicability of any additive language contained in an Award Agreement or other

written agreement which provides supplemental or additional terms not inconsistent with the Plan.

10.12 Governing Law. The Plan and all Awards will be governed by and interpreted in accordance with the laws of the

State of Delaware, disregarding any state’s choice-of-law principles requiring the application of a jurisdiction’s laws other than the

State of Delaware.

10.13 Claw-back Provisions. All Awards (including, without limitation, any proceeds, gains or other economic benefit

actually or constructively received by a Participant upon any receipt or exercise of any Award or upon the receipt or resale of any

Shares underlying the Award) shall be subject to the provisions of any claw-back policy implemented by the Company, including,

ANXA-10 PROXY STATEMENT 2023

䡵

Annex A

without limitation, any claw-back policy adopted to comply with Applicable Laws (including the Dodd-Frank Wall Street Reform and

Consumer Protection Act and any rules or regulations promulgated thereunder) as and to the extent set forth in such claw-back policy

or the Award Agreement.

10.14 Titles and Headings. The titles and headings in the Plan are for convenience of reference only and, if any conflict,

the Plan’s text, rather than such titles or headings, will control.

10.15 Conformity to Securities Laws. Participant acknowledges that the Plan is intended to conform to the extent

necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in

conformance with Applicable Laws. To the extent Applicable Laws permit, the Plan and all Award Agreements will be deemed

amended as necessary to conform to Applicable Laws.

10.16 Unfunded Status of Awards. The Plan is intended to be an “unfunded” plan for incentive compensation. With

respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement

shall give the Participant any rights that are greater than those of a general creditor of the Company or any Affiliate.

10.17 Relationship to Other Benefits. No payment under the Plan will be taken into account in determining any benefits

under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Affiliate

except as expressly provided in writing in such other plan or an agreement thereunder.

Notwithstanding the foregoing, if a Change in Control constitutes a payment event with respect to any Award (or portion of

any Award) that provides for the deferral of compensation that is subject to Section 409A, to the extent required to avoid the

imposition of additional taxes under Section 409A, the transaction or event described in subsection (a), (b), (c) or (d) with respect to

such Award (or portion thereof) shall only constitute a Change in Control for purposes of the payment timing of such Award if such

transaction also constitutes a “change in control event,” as defined in Treasury Regulation Section 1.409A-3(i)(5).

In addition, notwithstanding any provision herein to the contrary, in no event shall a Change in Control be deemed to have

occurred so long as DT holds Governing Rights. For purposes hereof, “Governing Rights” means DT’s rights with respect to the

governance of the Company that are substantially similar to or greater than the rights that DT possesses while it holds a “Voting

Percentage” of at least 30% pursuant to that certain Stockholders’ Agreement among the Company, DT and SoftBank Group Corp.

any incidental matters relating thereto; provided that any exercise of authority in conjunction with a determination of whether a

Change in Control is a “change in control event” as defined in Treasury Regulation Section 1.409A-3(i)(5) shall be consistent with

such regulation.

(subject in all respects to compliance with Section 423 of the Code).

8.2 Purchase of Shares

(a) An option held by a Participant that was granted under the Plan and that remains outstanding as of a Purchase Date

shall be deemed to have been exercised on such Purchase Date for the number of whole shares (rounding down to the nearest whole

share) equal to the aggregate funds accumulated in the Participant’s Account as of the Purchase Date divided by the applicable

Purchase Price (but not in excess of the number of shares for which options have been granted to the Participant pursuant to

Section 7.2).

(b) During the Purchase Period, shares of Common Stock that are to be acquired pursuant to the exercise of all or any

portion of an option shall be paid for by means of payroll deductions from Participants’ Eligible Compensation. Unless otherwise

determined by the Committee, any payroll deductions must be in one percent (1%) increments constituting not less than one percent

(1%) and not more than fifteen percent (15%) of a Participant’s Eligible Compensation received on each payday during the Purchase

Period; provided, however, that in no event shall the actual amount withheld through payroll deduction on any payday hereunder

exceed the net amount payable to the Eligible Employee on such payday after taxes and any other applicable deductions therefrom

(and if amounts to be withheld hereunder would otherwise result in a negative payment to the Eligible Employee on such payday, the

amount to be withheld hereunder shall instead be reduced by the least amount necessary to avoid a negative payment amount for the

Eligible Employee on such payday, as determined by the Committee). Payment amounts shall be credited on a bookkeeping basis to a

Participant’s Account under the Plan. All payroll deductions or contributions received or held by the Company may be used by the

Company for any purpose and the Company shall have no obligation to segregate such funds. No interest accrues on payroll

(d) Notwithstanding any provision in the Plan to the contrary, the Committee may allow Eligible Employees to

participate in the Plan via cash contributions instead of payroll deductions if the Committee determines that cash contributions are

permissible under Section 423 of the Code.

(e) Unless otherwise determined by the Committee, a Participant may suspend his or her payroll deductions or

contributions (i.e., by decreasing his or her rate of payroll deductions or contributions to zero) during an Offering Period by delivering

a notice of suspension to the Company or the Employer (in a manner p rescribed by the Committee) on or prior to the last day of the

month prior to the final month of such Offering Period (or by such other date as may be established by the Committee) and may not

increase his or her payroll deductions or contributions during an Offering Period. Any such suspension of payroll deductions or

contributions shall be effective as soon as practicable following the Company’s receipt of the new enrollment election form or such

other document as of the Committee may prescribe (but in no event later than the third full payroll period commencing after the payroll

period in which the new enrollment election form or other document, as applicable, is received by the Company, unless otherwise

determined by the Committee). If a Participant suspends his or her payroll deductions or contributions during an Offering Period, such

Participant’s cumulative unapplied payroll deductions or contributions prior to the suspension (if any) shall remain in his or her

account and shall be applied to the purchase of shares of Common Stock on the next occurring Purchase Date and such Participant

shall, at the end of such Offering Period be treated as having withdrawn from the Plan at the end of such Offering Period (unless such

Participant re-enrolls in the Plan for any subsequent Offering Period in accordance with Section 6). For clarity, if a Participant who

suspends participation in an Offering Period ceases to be an Eligible Employee or he or she withdraws from participation in such

Offering Period, in either case, prior to the Purchase Date next-following his or her suspension of participation in the Offering Period,

in any case, such Participant’s cumulative unapplied payroll deductions shall be returned to him or her in accordance with Section 9.

8.3 Refund of Excess Amount

Unless otherwise determined by the Committee, if, after a Participant’s exercise of an option under Section 8.2, an amount

remains credited to the Participant’s Account as of a Purchase Date (including after return of any amount pursuant to Section 7.2),

then the remaining amount shall be returned to the Participant, except that any amounts that are not sufficient to purchase a whole

share of Common S tock will be retained in the Participant’s Account for the subsequent Purchase Period or Offering Period, subject to

earlier withdrawal by the Participant as provided in Section 9.1. Notwithstanding the foregoing or anything to the contrary in the Plan,

the Committee may, in its sole discretion, provide that Participants shall purchase fractional shares of Common Stock on any Purchase

Date occurring in any future Offering Period and/or provide for the refund to Participants of the amounts remaining credited to their

respective Accounts at the end of any future Offering Period.

8.4 Pro Rata Allocation

If the total number of shares for which options are or could be exercised on any Purchase Date in accordance with this

Section 8, when aggregated with all shares for which options have been previously exercised under the Plan, exceeds the maximum

number of shares reserved in Section 4, the Company may allocate the shares available for delivery and distribution in the ratio that

the balance in each Participant’s Account bears to the aggregate balances of all Participants’ Accounts, and the remaining balance of

the amount credited to the Account of each Participant under the Plan shall be returned to him or her as promptly as possible.

8.5 Notice of Disposition

If a Participant or former Participant who is subject to United States federal income tax sells, transfers, or otherwise makes a

disposition of shares of Common Stock purchased pursuant to an option granted under the Plan within two (2) years after the date

such option is granted or within one (1) year after the date such shares were transferred to the Participant at the broker designated by

the Committee, then such Participant or former Participant shall notify the Company or the Employer in writing of such sale, transfer or

other disposition within ten (10) days of the consummation of such sale, transfer or other disposition. Without limiting the Participant’s

or former Participant’s ability to sell, transfer or otherwise make a disposition of shares and without limiting Section 3.2, Participants

and former Participants must, except as otherwise determined by the Committee, maintain any shares purchased pursuant to an

option granted under the Plan within two (2) years after the date such option is granted or within one (1) year after the date such

shares were transferred to the Participant at the broker designated by the Committee.

8.6 Conditions to Issuance of Shares

Annex B

conditions: (a) the admission of such shares of Common Stock to listing on all stock exchanges, if any, on which the shares of

Common Stock are then listed; (b) the completion of any registration or other qualification of such shares of Common Stock under any

state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental

regulatory body, that the Committee shall, in its absolute discretion, deem necessary or advisable; (c) the obtaining of any approval or

other clearance from any state or federal governmental agency that the Committee shall, in its absolute discretion, determine to be

necessary or advisable; (d) the payment to the Company of all amounts that it is required to withhold under federal, state or local law

upon exercise of the options, if any; and (e) the lapse of such reasonable period of time following the exercise of the rights as the

Committee may from time to time establish for reasons of administrative convenience.

SECTION 9. WITHDRAWAL FROM THE PLAN, TERMINATION

OF PARTICIPATION, AND LEAVE OF ABSENCE

9.1 Withdrawal From the Plan

A Participant may withdraw all funds accumulated in the Participant’s Account from the Plan during any Purchase Period by

delivering a notice of withdrawal to the Company or the Employer (in a manner prescribed by the Committee) on or prior to last day of

the month prior to the final month of the Purchase Period (or by such other date as may be established by the Committee). If notice of

complete withdrawal from the Plan as described in the preceding sentence is timely received, the Company or the Employer will cease

the Participant’s payroll withholding, or other contributions to the Plan, a nd in accordance with procedures established by the

Committee, either all funds then accumulated in the Participant’s Account shall be used to purchase shares on the Purchase Date for

such Purchase Period or all funds then accumulated in the Participant’s Account shall not be used to purchase shares but shall

instead be distributed to the Participant as soon as administratively feasible. An employee who has withdrawn from a Purchase Period

may not contribute additional funds to the Company or the Employer during that Purchase Period and require the Company or the

Employer to apply those funds to the purchase of shares. Any Eligible Employee who has withdrawn from the Plan in accordance with

this Section 9.1 may, however, reenroll in the Plan by the next subsequent Enrollment Date, if any, in accordance with Section 6.1.

9.2 Termination of Participation

Participation in the Plan terminates immediately on the date on which a Participant ceases to be employed by the Company or

the Employer for any reason whatsoever or otherwise ceases to be an Eligible Employee, and all funds then accumulated in the

Participant’s Account shall not be used to purchase shares of Common Stock but shall instead be distributed to the Participant (or in case

of the Participant’s death, to his or her estate, beneficiary or heirs, as applicable) as soon as administratively feasible, without interest.

9.3 Leave of Absence

If a Participant takes a leave of absence approved by the Company that meets the requirements of Treasury Regulation

Section 1.421-1(h)(2) under the Code, then a Participant may continue participation in the Plan by making cash payments to the

Company on his or her normal payday equal to the Participant’s authorized payroll deduction. Alternatively, such Participant shall have

the right, in accordance with procedures prescribed by the Committee, to elect to withdraw from the Plan in accordance with

Section 9.1. To the extent determined by the Committee or required by Section 423 of the Code, certain leaves of absence may be

treated as cessations of employment for purposes of the Plan.

SECTION 10. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION,

DISSOLUTION, LIQUIDATION, MERGER OR ASSET SALE

10.1 Adjustments Upon Changes in Capitalization

Subject to any required action by the stockholders of the Company, and in order to prevent dilution or enlargement of the

benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any outstanding

options under the Plan, the options to purchase shares covered by a current Offering Period, the number of shares that have been

authorized for issuance under the Plan, the maximum number of shares each Participant may purchase in each Offering Period or

Purchase Period (pursuant to Section 7.2(a)), as well as the price per share and the number of shares covered by each option under

the Plan that have not yet been purchased, shall be proportionately adjusted in the sole discretion of the Committee for any increase

or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend,

extraordinary cash dividend, combination or reclassification of the Common Stock, or recapitalization, reorganization, consolidation,

ANXB-6 PROXY STATEMENT 2023

䡵

Annex B

split-up, spin-off, or any other increase or decrease in the number of shares effected without receipt of consideration by the Company.

Except as expressly provided otherwise by the Committee, no issuance by the Company of shares of stock of any class, or securities

convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the

number or price of shares of Common Stock.

10.2 Adjustment Upon Dissolution, Liquidation, Merger or Asset Sale

Without limitation on the preceding provisions, in the event of any dissolution, liquidation, merger, consolidation, sale of all

or substantially all of the Company’s outstanding voting securities, sale, lease, exchange or other transfer of all or substantially all of

the Company’s assets, any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the

financial statements of the Company or any affiliate, or any changes in Applicable Law or accounting principles, or any similar

transaction or event as determined by the Committee in its sole discretion, the Committee may make such adjustment it deems

appropriate to prevent dilution or enlargement of rights in the number and class of shares that may be delivered under Section 4, in

the number, class or price of shares available for purchase under the Plan and in the number of shares that a Participant is entitled to

purchase and any other adjustments it deems appropriate. Without limiting the Committee’s authority under the Plan, in the event of

any such transaction or event, the Committee may elect to have the options hereunder assumed or such options converted or

substituted by a successor entity (or its Parent), to terminate all outstanding options either prior to their expiration or upon completion

of the purchase of shares on the next Purchase Date, to shorten the Offering Period by setting a new Purchase Date, or to take such

other action deemed appropriate by the Committee.

SECTION 11. DESIGNATION OF BENEFICIARY

Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named

contingently or successively) to whom the amount in his or her Account is to be paid in case of his or her death before he or she

receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a form

prescribed by the Committee, and shall be effective only when filed by the Participant in writing with the Company during the

Participant’s lifetime. In the absence of any such designation, any Account balance remaining unpaid at the Participant’s death shall

be paid to the executor or administrator of the Participant’s estate.

SECTION 12. MISCELLANEOUS

12.1 Restrictions on Transfer

Options granted under the Plan to a Participant may not be exercised during the Participant’s lifetime other than by the

Participant. Neither amounts credited to a Participant’s Account nor any rights with respect to the exercise of an option or to receive

shares of Common Stock under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way by the

Participant other than by will or the laws of descent and distribution or by a beneficiary designation as permitted by Section 11. Any

such attempted assignment, transfer, pledge, or other disposition shall be without effect, except that the Company may treat such act

as an election to withdraw from the Plan in accordance with Section 9.1.

12.2 Administrative Assistance

If the Committee in its discretion so elects, it may retain a brokerage firm, bank, or other financial institution to assist in the

purchase of shares, delivery of reports, or other administrative aspects of the Plan. If the Committee so elects, each Participant shall

(unless prohibited by Applicable Law) be deemed upon enrollment in the Plan to have authorized the establishment of an account on

his or her behalf at such institution. Shares purchased by a Participant under the Plan shall be held in such account in the

Participant’s name, or if the Participant so indicates in the enrollment form, in the Participant’s name together with the name of his or

her spouse in joint tenancy with right of survivorship or spousal community property, or in certain forms of trust approved by the

Committee. The Company may require that shares be retained with a broker or agent for a designated period of time and/or may

establish other procedures to permit tracking of disqualifying dispositions of such shares.

12.3 Death of Participant

In the event of a Participant’s death prior to the delivery to him or her of any shares or cash held by the Company for the

account of the Participant, and to the extent permitted by Applicable Law, the Company shall deliver such shares or cash to the

Participant’s estate, beneficiary or heirs, as applicable.

Annex B

12.4 Tax Withholding

At the time a Participant’s options under the Plan are exercised, in whole or in part, or at the time some or all of the

Participant’s shares issued under the Plan are disposed of, the Participant must make adequate provision for the Company’s or the

Employer’s federal, state, or other tax withholding obligations, if any, that arise upon the exercise of the right or the disposition of the

shares. At any time, the Company or the Employer may, but shall not be obligated to, withhold from the Participant’s compensation or

shares received pursuant to the Plan the amount necessary for the Company or the Employer to meet applicable withholding

obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits

attributable to sale or early disposition of shares by the Participant.

12.5 Equal Rights and Privileges

All Eligible Employees shall have equal rights and privileges with respect to the Plan so that the Plan qualifies as an

“employee stock purchase plan” within the meaning of Section 423 or any successor p rovision of the Code. Notwithstanding the

express terms of the Plan, any provision of the Plan that is intended to comply with Section 423 that is inconsistent with Section 423

or any successor provision of the Code shall without further act or amendment by the Company or the Committee be reformed to

comply with the requirements of Section 423 of the Code. This Section 12.5 shall take precedence over all other provisions in the

Plan.

12.6 Governing Law

The Plan shall be governed by the substantive laws (excluding the conflict of laws rules) of the State of Delaware.

12.7 Amendment, Suspension and Termination

(a) The Board may amend, suspend or terminate the Plan at any time; provided, however, that (i) the Plan may not be

amended in a way that will cause options issued under the Plan to fail to meet the requirements of Section 423 of the Code; and

(ii) no amendment that would amend or modify the Plan in a manner requiring stockholder approval under Section 423 of the Code or

the requirements of any securities exchange on which the shares are traded shall be effective unless such stockholder approval is

obtained. No options may be granted during any period of suspension of the Plan.

(b) Without stockholder consent and without regard to whether any Participant rights may be considered to have been

adversely affected and to the extent permitted by Section 423 of the Code, the Committee shall be entitled to change or terminate the

Offering Periods, limit the frequency and/or number of changes in the amount withheld from a Participant’s Eligible Compensation

during an Offering Period or the amount of the contribution, as applicable, establish the exchange ratio applicable to amounts

withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a Participant in order

to adjust for delays or mistakes in the Company’s processing of payroll withholding elections, establish reasonable waiting and

adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of shares for

each Participant properly correspond with amounts withheld from the Participant’s Eligible Compensation, and establish such other

limitations or procedures as the Committee determines in its sole discretion to be advisable that are consistent with the Plan.

accounting consequences, the Committee may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to

reduce or eliminate such accounting consequence including, but not limited to:

(i) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the

change in Purchase Price;

(ii) shortening any Offering Period so that the Offering Period ends on a new or earlier Purchase Date, including

an Offering Period underway at the time of the Committee action;

(iii) allocating shares of Common Stock; and

(iv) such other changes and modifications as the Committee determines are necessary or appropriate.

Such modifications or amendments shall not require stockholder approval or the consent of any Participant.

(d) If the Plan is terminated, the Committee may elect to (i) terminate all outstanding options either prior to their

expiration or upon completion of the purchase of shares on the next Purchase Date, (ii) permit options to expire in accordance with

their terms (and participation to continue through such expiration dates), or (iii) shorten the Offering Period so that the purchase of

PROXY STATEMENT 2023

䡵

Annex B

shares occurs prior to the termination of the Plan. If the options are terminated prior to expiration, all funds accumulated in

Participants’ Accounts as of the date the options are terminated shall be returned to the Participants as soon as administratively

feasible, without any interest thereon.

12.8 No Right of Employment

Neither the grant nor the exercise of any rights to purchase shares under the Plan nor anything in the Plan shall impose upon

the Company or the Employer any obligation to employ or continue to employ any employee or Participant. The right of the Company

or the Employer to terminate any employee shall not be diminished or affected because any options to purchase shares of Common

Stock have been granted to such employee. The grant of an option hereunder during any Offering Period shall not give a Participant

any right to similar grants hereunder.

12.9 Rights as Stockholder

No Participant shall have any rights as a stockholder with respect to shares of Common Stock acquired under the Plan

unless and until such shares of Common Stock have been issued to him or her (as evidenced by the appropriate entry on the books of

the Company or of a duly authorized transfer agent of the Company). Until such shares are issued, a Participant will only have the

rights of an unsecured creditor with respect to such shares. No adjustments shall be made for dividends (ordinary or extraordinary,

whether in cash securities, or other property) or distribution or other rights for which the record date occurs prior to the date of such

issuance, except as otherwise expressly provided herein or as determined by the Committee.

12.10 Other Jurisdictions

Without amending the Plan, the Committee may establish procedures to grant options or otherwise provide benefits to

Eligible Employees of Designated Companies on such terms and conditions different from those specified in this Plan as may, in the

judgment of the Committee, be necessary or desirable to foster and promote achievement of the purposes of the Plan and shall have

the authority to adopt such modifications, procedures, separate Offerings, subplans and the like as may be necessary or desirable

(a) to comply with provisions of the laws or regulations or conform to the requirements to operate the Plan in a qualified or tax or

accounting advantageous manner in other jurisdictions in which the Company or any Designated Companies may operate or have

employees, (b) to ensure the viability of the benefits from the Plan to Eligible Employees employed in such jurisdictions and (c) to

meet the objectives of the Plan. Notwithstanding anything to the contrary herein, any such actions taken by the Committee with

respect to E ligible Employees of any Designated Companies may be treated as a separate Offering under Section 423 of the Code or a

subplan outside of an “employee stock purchase plan” under Section 423 of the Code and not subject to the requirements of

Section 423 set forth in the Code and this Plan.

12.11 Governmental Regulation

The Company’s obligation to sell and deliver shares of Common Stock under the Plan is subject to the approval of any

governmental authority required in connection with the authorization, issuance, or sale of such shares. The Company shall not be

required to issue shares of Common Stock with respect to an option unless the exercise of such option and the issuance and delivery

of such shares pursuant thereto shall comply with all the applicable provisions of law, including, without limitation, the Securities Act

of 1933, as amended, the Securities Exchange Act of 1934, as amended, the rules and regulations promulgated thereunder, a nd the

requirements of any stock exchange upon which the shares may then be listed.

12.12 Code Section 409A

The Plan and the options granted hereunder are intended to be exempt from the application of Section 409A of the Code

and the other interpretive guidance issued thereunder (“Section 409A”), and any ambiguities herein will be interpreted to so as to

exempt the Plan and such options from Section 409A. In furtherance of the foregoing and notwithstanding any other provision in the

Plan to the contrary, if the Committee determines that an option granted under the Plan may be subject to Section 409A or that any

provision of the Plan would cause an option under the Plan to be subject to Section 409A, the Committee may amend the terms of the

Plan and/or of an outstanding option granted under the Plan, and/or adopt other policies and procedures (including amendments,

policies and procedures with retroactive effect), or take such other action that the Committee determines is necessary or appropriate,

in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan

from or to allow any such options to comply with, Section 409A. Notwithstanding the foregoing, the Company shall have no liability to

a Participant or any other party if the option to purchase Common Stock under the Plan that is intended to be exempt from or

䡵

PROXY STATEMENT 2023

ANXB-9

Annex B

compliant with Section 409A is not so exempt or compliant or for any action taken by the Committee with respect thereto. The

Company makes no representation that any option to purchase Common Stock under the Plan is compliant with Section 409A.

12.13 Limitations on Liability

Notwithstanding any other provisions of the Plan, no individual acting as a director, officer, other employee or agent of the

Company or any Subsidiary will be liable to any Participant, former Participant, designated beneficiary or any other person for any

claim, loss, liability, or expense incurred in connection with the Plan or any Offering Period, and such individual will not be personally

liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as a member of the

Committee, director, officer, other e mployee or agent of the Company or any Subsidiary. The Company will indemnify and hold

harmless each director, officer, other employee and agent of the Company or any Subsidiary that has been or will be granted or

delegated any duty or power relating to the Plan’s administration or interpretation, against any cost or expense (including attorneys’

fees) or liability (including any sum paid in settlement of a claim with the Committee’s approval) arising from any act or omission

concerning this Plan unless arising from such person’s own fraud or bad faith.

12.14 Data Privacy

As a condition for participation in the Plan, each Participant explicitly and unambiguously consents to the collection, use

and transfer, in electronic or other form, of personal data as described in this Section 12.14 by and among the Company and its

Subsidiaries and affiliates exclusively for implementing, administering and managing the Participant’s participation in the Plan. The

Company and its Subsidiaries and affiliates may hold certain personal information about a Participant, including the Participant’s

name, address and telephone number; birthdate; social security, insurance number or other identification number; salary; nationality;

job title(s); any shares of Common Stock held in the Company or its Subsidiaries and affiliates; and participation details, to implement,

manage and administer the Plan and any Offering Period(s) (the “Data”). The Company and its Subsidiaries and affiliates may transfer

the Data amongst themselves as necessary to implement, administer and manage a Participant’s participation in the Plan and any

Offering Period(s), and the Company and its Subsidiaries and affiliates may transfer the D ata to third parties assisting the Company

with Plan implementation, administration and management. These recipients may be located in the Participant’s country, or

elsewhere, and the Participant’s country may have different data privacy laws and protections than the recipients’ country. By

participating in any Offering Period under the Plan, each Participant authorizes such recipients to receive, possess, use, retain and

transfer the Data, in electronic or other form, to implement, administer and manage the Participant’s participation in the Plan,

including any required Data transfer to a broker or other third party with whom the Company or the Participant may elect to deposit

any shares of Common Stock. The Data related to a Participant will be held only as long as necessary to implement, administer, and

manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data that the Company holds regarding

such Participant, request additional information about the storage and processing of the Data regarding such Participant, recommend

any necessary corrections to the Data regarding the Participant or refuse or withdraw the consents in this Section 12.14 in writing,

without cost, by contacting the local human resources representative. If the Participant refuses or withdraws the consents in this

Section 12.14, and the Company may cancel Participant’s ability to participate in the Plan or any Offering Period(s). For more

information on the consequences of refusing or withdrawing consent, Participants may contact their local human resources

representative.

12.15 Severability

If any portion of the Plan or any action taken under it is held illegal or invalid for any reason, the illegality or invalidity will

not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been

excluded, and the illegal or invalid action will be null and void.

12.16 Relationship to Other Benefits

No payment under the Plan will be taken into account in determining any benefits under any pension, retirement, savings,

profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as expressly provided in writing

in such other plan or an agreement thereunder.

12.17 Condition for Participation

As a condition to participation in the Plan, Eligible Employees agree to be bound by the terms of the Plan (including,

without limitation, the notification requirements of Section 8.5) and the determinations of the Committee.
